LOG: [4/15][Clang][RISCV][NFC] Remove unnecessary logic under RVVIntrinsic::computeBuiltinTypes

`PolicyAttrs::IsUnspecified` is modified in
`RVV::Intrinsic::computeBuiltInTypes` and used under
`RVVIntrinsic::updateNamesAndPolicy`. Suprisingly the modification
in `RVV::Intrinsic::computeBuiltInTypes` is completely unnecessary.
This commit removes the redundant logic.

This is the 4th 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.
