Convert the allowed-ships and allowed-weapons lists to sets, rather than naive vectors that stored a true/false for every class. Since these are ordered sets, iteration occurs in the same sequence as iteration of `Ship_info` or `Weapon_info`. Associated data structures such as `Granted_ships` and `Granted_weapons` are converted as well.

Ship_info is already an SCP_vector but MAX_SHIP_CLASSES (500) is held in
place by fixed-size structures throughout the engine and editors. This
converts the seven file-format-adjacent arrays whose persistence touches
the .csg campaign save and .plr pilot file formats:
campaign::ships_allowed [MAX_SHIP_CLASSES] -> SCP_vector<ubyte>
campaign::weapons_allowed [MAX_WEAPON_TYPES] -> SCP_vector<ubyte>
loadout_data::ship_pool [MAX_SHIP_CLASSES] -> SCP_vector<int>
loadout_data::weapon_pool [MAX_WEAPON_TYPES] -> SCP_vector<int>
scoring_struct::kills [MAX_SHIP_CLASSES] -> SCP_vector<int>
scoring_struct::m_kills [MAX_SHIP_CLASSES] -> SCP_vector<int>
scoring_struct::m_okKills [MAX_SHIP_CLASSES] -> SCP_vector<int>
The CSG and PLR file formats already store explicit counts and key by
ship/weapon names, so no on-disk format change is needed. Existing
read/write loops already iterated by ship_info_size() / weapon_info_size()
and just compile through against the new vector types.
Vectors are sized to ship_info_size() / weapon_info_size() in
scoring_struct::init(), mission_campaign_clear(), player_loadout_init(),
and the campaign-pool reset paths in csg.cpp and multi_campaign.cpp.
All of these run after weapon_init() / ship_init(), so the sizing
invariant holds. scoring_struct globals constructed at static-init time
start with empty vectors; first index access is always post-table-parse.
Multiplayer stats sync (multimsgs.cpp) now derives offsets and counts
from the vector size; added USHRT_MAX assertions on the sender side
since the wire protocol packs offset/count as USHORT. The FSTracker
sync (multi_fstracker.cpp) clamps vmt->num_ships down to the local
mod's kills.size() before transmission and guards the receive-side
write so a tracker payload with more ship slots than this mod has won't
overrun the vector.
The MAX_SHIP_CLASSES cap itself stays in place at ship.cpp:2327; this
is one prerequisite toward lifting it. The other ~25 fixed-size
ship-class-indexed structures (team_data, Ss_pool_teams, Wl_ships,
FRED2 editor arrays, qtFRED Editor::_ship_usage, etc.) remain to be
addressed in follow-up PRs.

This introduces a new mechanism for handling bit flags. Instead of using an int (or two, or three) to write bits into, this uses the std::bitset in a wrapper class that accepts an enum class as input. This means that certain classes of errors we've had a few of in the engine, where a coder used the wrong set of flags or checked them against the wrong variable (SF_STEALTH vs SIF_STEALTH, for example) can now be detected at a compiler level rather than not at all.
