Remove BaseDomain use in LoaderAllocator and event tracing helpers (dotnet#107481)

- Remove `BaseDomain` member on `LoaderAllocator`
  - Add asserts in functions using `AppDomain` that the loader allocator is collectible and the type is `LAT_Assembly` (so `AssemblyLoaderAllocator` which always had `AppDomain`)
- Remove unnecessary `BaseDomain`/`AppDomain` parameters from event tracing helpers
  - They were always being called with the current app domain
