[Yosry Ahmed <yosry.ahmed@linux.dev>]

Add more test cases for the selective CR0 write intercept, covering bugs
fixed by
https://lore.kernel.org/kvm/20251024192918.3191141-1-yosry.ahmed@linux.dev/.

Patches 1-6 are cleanups and prep work. Patch 7 generalizes the existing

- Fixed author and Signed-off-by.
- Added fix for skip return codes.
