Stabilize Vulkan shadow pipeline diagnostics and compatibility path

Browse source 
- Fix shadow depth image layout transitions by tracking per-frame old/new layouts.
- Update receiver shadow projection to Vulkan clip-depth convention.
- Test inverted shadow compare op path (GREATER_OR_EQUAL).
- Switch shadow compare samplers to NEAREST filtering for broader Vulkan compatibility.
- Expand shadow caster coverage by disabling caster cull filtering in WMO/M2/Character shadow pipelines.
- Keep light-space matrix path on stable character-centered framing.
