Refactor TableSchemaResolver to remove `includeMetadataFields` flags

Currently, `TableSchemaResolver` to pass `includeMetadataFields` in its APIs that would selectively remove metadata fields from the returned schemas. There are multiple issues with this flag:
# It's applied inconsistently: sometimes it just means that meta fields {_}won't be added{_}, and sometimes it means fields _would be removed_ even if present
# This flag actually spells the usage context into TableSchemaResolver: it's highly contextual whether caller wants to remove, omit such meta-fields, or take the schema as is and should not be spilled into the Resolver itself.
# B/c of it there's no way to know actually what was actual schema the data was written with (b/c flag might not only omit, but also change the original schema)
