5x Fix cache performance issues (#6616)

Calling `getObjectMetadata` from `WorkspaceCacheStorageService` in every
query was causing big performance issues. The `objectMetadataCollection`
is now part of the `WorkspaceInternalContext` so we only instance it
once in the `WorkspaceDatasourceFactory`.
Queries are now much faster, for instance for TimelineCalendar, it went
from ~450ms to 80ms.
