Remove dead code from legacy metadataVersion cache mechanism (#23122)

- Drop unused setORMEntitySchema/getORMEntitySchema from
WorkspaceCacheStorageService
- Drop MetadataObjectMetadataMaps cache key, only referenced by the
flush loop
- Drop never-populated workspaceMetadataVersion field from workspace
auth context type and builders
- Drop unthrown TwentyORMExceptionCode.METADATA_VERSION_MISMATCH
- Drop unused WorkspaceMetadataVersionModule imports in field-metadata
and object-metadata modules
