* Fix asteroids spawning outside active fields
Found an interesting edge case bug with active asteroid fields that has been present since retail: if a large ship is just outside an active asteroid field, that field will end up spawning asteroids outside the field bounds. This is because the game thinks that the large ship is within the asteroid field when it is actually not. Specifically, the check `asteroid_is_ship_inside_field` does not properly account for the ship the addition of the ship's diameter to the bounding box check.
This PR adds a flag to fix that bounding box check and fix the bug of spawing asteroids outside the asteroid field bounds. Note, `asteroid_is_ship_inside_field` is used twice in the code, once within `set_asteroid_throw_objnum` and once following that call within `maybe_throw_asteroid`. Also note, `asteroid_in_inner_bound` uses a delta of 0 in all cases except when being called within `asteroid_is_ship_inside_field`.
Tested and this fixes the bug while still having asteroid fields work as expected. (Also took this chance to rename a local variable for newly create asteroids to more descriptive name).

Update assertion message and mission saving check since older builds are not going to be able to read fields created with newer builds
* update to use empty
The Unlimited Asteroid/Debris Field Types & Subtypes PR (#6021) updated to using vectors to allow for unlimited asteroid and debris types. That update removed the count field, `num_used_field _debris_types`, which counted both asteroids and debris pieces (even though the name only has debris in it). The counter variable was removed in favor of `.size()` but now both asteroid and debris field sizes needed to be checked, so this PR updates the code to account for that. Allows asteroid fields to properly pass the count check and properly again spawn in mission.
Tested on asteroid fields passive and active along with debris fields (both created from sexps and the asteroid mission editor) and everything now works as expected. Also tested on missions with no fields and those also still work as expected.

As requested by Event Horizon, this removes the limit on fireball types. The fixed array has been replaced with a vector and the relevant code updated accordingly. There is also a new version of `stuff_int_list()` to parse ints into a vector.
This also adds bounds checking for explosion animations that are parsed for ship classes, ship types, and asteroids, since previously there was no guarantee that the indexes would be in range.
There were a few instances of `Random::next()` being called without ensuring its arguments couldn't trip an assertion. This should hopefully catch them all.
* Allow Modders to Set Rotational Scaling Multiplier for Asteroids/Debris
Previously, there was no way to limit the velocity at which asteroids/debris randomly rotated. There was a way to set maximum speed, thus this PR follows that convention and adds a way to cap the rotational velocity scaling. This PR allows modders to set caps per type, including setting the value to 0 for no rotation.
A single scaling value was used b/c it was the most straightforward value to se via table and it was the employed the least code changes. Asteroids pick a random normalized vector for their rotation when spawning, and then that value is scaled by a random multiplier.
* use full multiplier instead
Add `const` to the `mc_info` struct so its values aren't inadvertently overwritten. Tweak some of the collision code to prevent overwrites.
Also remove the `flak_muzzle_flash` declaration since that function no longer exists.
* refactor how asteroid wrapping is done and setup for allowing or disallowing range check

Chucked asteroids are always large. Therefore use their speed, not the
speed of the 1st parsed/small asteroid. Should not affect retail because
it uses the same speed for all three asteroids
This initializes `mc_info` to the correct values when it is constructed, removing the need for `mc_info_init`.
This PR also fixes a group of incorrectly inverted assignments in beam.cpp.
PR #5058 made `count_incident_asteroids()` use `Asteroid_obj_list` instead of `obj_used_list`; a perfectly sensible change in and of itself. However, PR #4827 had previously made `asteroid_obj_list_init()` only be called if FRED wasn't running (presumably because of the iteration through `Asteroid_objs` to clear flags, which is wasted effort in FRED). The problem is that without `list_init()` being called on `Asteroid_obj_list`, its `prev` and `next` were `nullptr` instead of linking back to itself, which means the beginning of the list and the end of the list were no longer considered the same (the iterator's `begin()` calls `GET_FIRST(head)`, which is effectively `head->next`, while `end()` calls `END_OF_LIST(head)`, which is effectively just `head`). This meant that iterating over `list_range(Asteroid_obj_list)` was returning `nullptr` as the first element of the list, and trying to dereference that would cause a crash. This was still not a problem in and of itself, as long as nothing tried to iterate over `Asteroid_obj_list` while FRED was running, which theoretically shouldn't be necessary...
PR #3704 changed mission parsing so that when parsing a ship with a name that matches one of the `Asteroid_field.target_names`, it would call `asteroid_add_target()` to initialize the relevant data for the asteroid field to fling asteroids at that ship. `asteroid_add_target()` calls `count_incident_asteroids()`, which (since PR #5058) iterates over `Asteroid_obj_list`, causing a crash due to dereferencing a null pointer on any mission that defines `$Asteroid Targets:` (and then actually has such a target be parsed).
While this could be solved by unconditionally initializing `Asteroid_obj_list`, there's really no need to do anything with `Asteroid_obj_list` in FRED, so instead the `asteroid_add_target()` call has been gated behind a `!Fred_running` check, and `Assertion()`s have been added to make sure `Asteroid_obj_list` has been initialized at the beginning of any function that does anything with it (besides initialize it), to catch similar problems in the future.
Fixes#5092.
Follow-up to #5040. This extends the checks to most iterations over `obj_used_list` in FSO. There are a few exceptions such as `waypoint_add` and `waypoint_remove`, plus a few others. And none of the object iterations in FRED have the guard because FRED does not use the same object life cycle as FSO.
When iterating through `Ship_obj_list`, check the `Should_be_dead` flag before using the object. This fixes#4990 and adds defense-in-depth checks to guard against similar errors elsewhere.
I considered moving the `Ship_obj_list` removal from `obj_delete` to `ship_cleanup`, but decided it would be prudent to avoid fundamental changes to lifecycle management.

Adds gravity! Applies on a per-mission basis, and weapons, ships, debris, and asteroids now have a configurable "gravity const" which multiplies the effect of gravity on them, by default everything except debris is 0 (meaning no effect even when the mission has gravity). AI and the lead indicator will also lead for ballistic trajectories as well, given a gravity-affected weapon. No FRED support or gravity direction control yet, to come in later PRs.
Some refactoring with asteroid fields:
1. Moves asteroid throwing targets into the Asteroid_field struct, in anticipation of potentially multiple fields in the future
2. Moves some initialization code into `asteroid_level_init`
3. Calls `asteroid_level_init` when a mission is cleared
4. Loads asteroid targets as part of the asteroid field update/init logic. This fixes a FRED bug reported in Discord where asteroid targets stay in the dialog when a new mission is loaded
5. Remove `Default_asteroid_throwing_behavior` flag as it is equivalent to checking that the target list is empty
