Backport UpdateAddOnMemoryUsage / GetAddOnMemoryUsage and the script
profiling family (scriptProfile, GetFunctionCPUUsage, UpdateAddOnCPUUsage,
GetAddOnCPUUsage, GetFrameCPUUsage, GetEventCPUUsage, GetScriptCPUUsage,
ResetCPUUsage), mirroring 3.3.5's engine mechanism.
- Gc::Hooks owns the GC lifecycle hooks (luaC_link, newlstr,
luaS_newudata, freeobj); Gc::Tag stamps each new object with the
engine's context word (3.3.5's lua_tainted rule) and sums sizes with
the engine's own free sizes.
- lua_gctag pins: the addon load window (two call patches in
FUN_ADDON_LOAD_ONE) and template application (engine single-name
sites + Xml::Inherits lists).
- Profile::Cpu keeps 3.3.5's per-closure Profile records through Lua's
own call/return hook, installed only when scriptProfile is 1; tail
calls, error unwinds and coroutines handled.
- ScriptArgs observers time every handler run; signals counted at each
dispatcher (call-site redirect inside FUN_FIRE_EVENT, not a MinHook).
- Frame::ScriptSlots enumerates a frame's script slots without creating
them, for GetFrameCPUUsage.
- Add the unordered_dense submodule (v5.3.2); share ResolveRecord via
addons/Registry; fix the AddOnEntry inline-name comments.
