  [RISCV] Mark HW shadow stack ops as frame setup/destroy (#203362)

This change follows up on PR #200182 and addresses the issue in the
[related
comment](https://github.com/llvm/llvm-project/pull/200182#discussion_r3329197379).

It sets `FrameSetup` on SSPUSH/C_SSPUSH and `FrameDestroy` on SSPOPCHK
instructions emitted by RISCVFrameLowering for the HW shadow stack path.
The test was written manually (instead of using
`utils/update_mir_test_checks.py`) to keep it simple and avoid
unnecessary fragility.
