Each base class virtual is named after what its overrides do and how
callers use it, e.g. AttCheck::calcMtx (0x710108a614) is the virtual
that AttClient calls before testing its checks.

Each file moves to where its code is linked, and namespaces follow the
new paths. ASSettingMgr is an unofficial name.

| Old | New |
|---|---|
| act::ASSetting (ActorSystem/actASSetting) | res::ASSettingMgr (Resource/Actor/resResourceASSettingMgr) |
| Resource/resResourceASSetting, Resource/Actor/resResourceASResourceExtension | Resource/Actor/resResourceASSetting |
| ksys::DebugFinder (System/DebugFinder) | ksys::act::DebugFinder (ActorSystem/actDebugFinder) |
| ActorSystem/LOD/actLodState | ActorSystem/actLodState |
| ActorSystem/actAiRoot | ActorSystem/aiRootAi |
| Map/mapStagePreActorCache | System/StagePreActorCache (ksys) |

ActorFactory's static initialiser fills its table with uking actor
ctors. CurrentResNameMgr (0x71010b770c) links in KingSystem/System right
before GameConfig.

Equivalent, shorter, more readable, and matching!

This reverts commit 42807160cfb33af9f3cf2fa6b0ba98f232208cdb.

It makes searching for NON_MATCHING comment descriptions much less
convenient in most text editors or IDEs, and we want the function
CSV to be the single source of truth for function statuses. Having
a function marked as matching but not built because of a stray #ifdef
would be bad.

Turns out they are just value-initialised aggregates.
