[5/7][Clang][RISCV] Remove default tail-undisturbed for vcompress intrinsics

[eopXD]

Summary

The destination parameter is removed for non-policy unmasked intrinsics.

The default policy for non-policy (implicit) vcompress intrinsics will
be tail agnostic and mask undisturbed.

This is the 5th commit of a patch-set that aims to remove the
IsPrototypeDefaultTU special case for the rvv-intrinsics.

Please refer to the cover letter in the 1st commit (D140895) for an
overview.
