ksys/act: split IDamageManager out of DamageManagerBase

DamageManagerBase's root base class (previously
DamageManagerBase_UnknownBase1) holds the damage callback list, and its
code is linked among the ActorSystem objects rather than with the
Game/Actor/Damage files. It appears to be an engine-side abstract base,
so let's move it to KingSystem/ActorSystem as ksys::act::IDamageManager
(unofficial name, following the ksys IManager/Manager pattern and
Actor::getDamageMgr), together with DamageCallback and Struct20Base, and
have Actor::getDamageMgr return it. DamageManagerBase now overrides its
getters and inherits addDamageCallback/removeDamageCallback from it.

The rest of the damage code stays in Game/Actor/Damage but is regrouped
to match link order: Struct20::combineMaybe moves into
actDamageManagerBase.cpp, Struct20::reset becomes inline and
dmgStruct20.cpp becomes actDamageMgr.cpp. The uking::dmg namespace is
merged into uking::act, so the files there take the act prefix too, and
dmgInfoManager becomes actDamageInfoMgr after the class it holds.
