Although normalized vectors in FSO are supposed to stay normalized, occasionally small floating point errors can pop up. In most cases these do not cause a problem, but in certain cases these errors can rapidly accumulate and corrupt an otherwise well-behaved matrix. This can most easily be seen with daisy-chained dock sequences or docked ships with angled dockpoints.
This PR audits the usage of `vm_vector_2_matrix_norm` to re-normalize vectors in cases where floating point errors could accumulate. There are also a few new Assertions for extra vigilance.
Follow-up to #6596. Fixes#6634.
* base working version
* localization and minor tweaks
* add retail UI controls
* Add way to hide gauges from Config view
* convert hud config from index matching to id matching
* clang
Most places in the code that use `vm_vector_2_matrix` do so on already-normalized vectors. Changing these to `vm_vector_2_matrix_norm` avoids redundant normalization.
* Add scaling for vfnts and scale multipler to gr_string
* nullptr
* Add scaling to a couple other string operations
* Add scaling features to additional bitmap drawing methods
* Implement framework for rendering hud gauges in config mode
* fix merge error
* address feedback
Make these convenient functions even more convenient:
1. Change `object_get_model()` to `object_get_model_num()` and `object_get_model_instance()` to `object_get_model_instance_num()` to more accurately reflect what they do
2. Add new `object_get_model()` and `object_get_model_instance()` functions to return `polymodel*` and `polymodel_instance*` values.
A recent-ish FSO feature, `$Turret Name:`, allows turrets to be displayed differently on the HUD depending on the weapon they carry. It is useful for scripts to be aware of this, so this PR adds a `TurretName` virtvar for weapon classes, as well as a `NameOnHUD` virtvar for subsystems. The `NameOnHUD` virtvar shares exactly the same code as the HUD uses, so any future HUD modifications will be reflected in scripting as well. This required a small amount of refactoring: changing `get_turret_subsys_name()` to return a value rather than stuffing a string, renaming it to `ship_subsys_get_name_on_hud()`, and moving it to ship.cpp.

This advances the versions for Clang to 16 and GCC to 13 along with
fixing any warnings these new versions are detecting now.
The new image versions also include Vulkan so the additional workflow
step for installing that is not necessary anymore.
Add `const` to the `eval_enemy_obj_struct` struct so its values aren't inadvertently overwritten. Handle a bit of const-correctness propagation. Also add default member initialization to the struct.

1. Deprecate the old set-jumpnode-name sexp now that there is a set-jumpnode-display-name
2. Make the display name design consistent with ships and weapons; in particular add a `HasDisplayName()` function and automatically generate the display name for hash-truncated names
3. Keep the display name in sync when the name is changed in the FRED dialog
4. Fix the overriding of hash-truncated names with display names on the HUD
5. Fix the incorrect setting of the alphacolor flag when using FRED
6. Fix array out-of-bounds access when no object is selected

Allow different types of cargo scans, including the -dualscanline behavior, to be specified in the HUD gauges table. Right now the options are "default" and "dualscanlines".
In #4443, `fl_near_zero` was set to use default epsilon values in the `IS_VEC_NULL` check. In this comparison, epsilon is the wrong threshold because it used to have a much smaller threshold. The fix restores the previous definitions of `IS_VEC_NULL` and `IS_VEC_NULL_SQ_SAFE` by exposing the epsilon value as an optional parameter (similar to how `IS_NEAR_ZERO` used to work. This PR also restores `IS_VEC_NULL_SQ_SAFE` where it was replaced by `IS_VEC_NULL.`
* more cleanup in preparation for model translation
1) Clean up stepped rotation, fixing some logic, adding safeguards for invalid values, and allowing rotations to go in the opposite direction
2) Add more specific SEXP error checking for AWACS and rotating subsystems
3) Assorted refactoring and polishing
* address feedback, plus a bit of extra cleanup
Several things going on here:
1) refactor `get_display_string()` to `get_display_name()` to be more precise
2) likewise, refactor `alt_name` to `display_name`
3) automatically generate display names when parsing the ship, ship class, and weapon class for the first time
4) remove the on-the-fly truncation of names with hash symbols
Basically this subsumes the `end_string_at_first_hash_symbol` logic into the display name. Rather than truncate the name every time it's displayed, truncate it once when it's parsed. This takes advantage of the previous display name infrastructure, since display names are a superset of the case of truncating the hash symbol.
This also has the benefit of now allowing hash symbols within display names. When updating Destiny of Peace, I noticed that "Lockheed Shuttle #4" would no longer display properly; and it was not previously possible to fix this even with display names.
I could pull out the `get_display_string()` and `alt_name` renaming into a separate PR if desired.
