After this PR, we will grant permissions on internal tables of MVs, when we grant permissions on the MV itself.

Can we also extend this to sinks and indexes?

After this PR, The select privilege on an index will be granted or revoked correspondingly with its primary table. This PR also supports grant and revoke select privilege for sink, which means user with select privilege on sink can query its internal tables now. Cc @kwannoel PTAL.
