  [msan] Support most Arm NEON vector shift instructions (#102507)

This adds support for the Arm NEON vector shift instructions that follow
the same pattern as x86 (handleVectorShiftIntrinsic).

VSLI is not supported because it does not follow the 2-argument pattern
expected by handleVectorShiftIntrinsic.

This patch also updates the arm64-vshift.ll MSan test that was
introduced in
