[Local GC] Implement loader protocol for a standalone GC (#14663)
* First cut of the load protocol * Implement for non-standalone GC * Initial working implementation * First steps towards not using GetProcAddress when not using a standalone GC * Factor out loading routines into standalone and non-standalone cases * Remove the FEATURE_STANDALONE_GC_ONLY build * Code cleanup and comments * Comments for the version numbers * Use more appropriate type for config string * add GC_LOAD_STATUS_BEFORE_START to disambiguate failures before the start of the load and failures at the beginning of the load * FEATURE_STANDALONE_GC on by default * Implement YieldProcessor and MemoryBarrier for arm and arm64 * Remove missed FEATURE_STANDALONE_GC feature check
