refactor(entity): each component type has an allocator, as the client

DoObjectComponentLoad walks the client's load order and calls the type's
allocator from a table, like ObjectLoader2, instead of one 76-case switch.
Components with rules of their own have a static Allocator (the client's
LWOxComponent::Allocator); the rest share a registry allocator. The load
state moves to ObjectLoadState.h so the allocators can take it.

Construction bytes are identical for all 15,962 LOTs.
