ksys/act: rename the actor accessor to ActorLinkConstDataAccess

The 0x18-sized accessor appears to be named ActorLinkConstDataAccess
based on a source path string in the Wii U build. The 0x10-sized
base class (which we had given the name to) only holds a BaseProc and
its dtor/acquire functions live in a separate TU so let's rename it
BaseProcAccessor (unofficial name).

acquireActor is a header inline whose one copy landed in the BeamBase
object. Nothing in BeamBase calls it, so the BeamBase function that used
it was probably dead-stripped by the linker.
