[10/15][Clang][RISCV][NFC] Don't need to check for `MaskPolicy` in `isTAPolicy` and...

Caller of the two utilities is always companied with a predicate to
check for `!IsMask`, so we don't need to check for the mask policy
here.

This also removes dependency to `Policy::PolicyType::Omit`, which will
be removed.

This is the 10th commit of a patch-set that aims to change the default policy
for RVV intrinsics from TAMU to TAMA.

Please refer to the cover letter in the 1st commit (D141573) for an
overview.
