Fix ART Blit detection regression and add D24S8 <-> RGBA8 conv to Vulkan

This was regressed by ART.
Prior to ART, the screenshots were saved at the title's framebuffer resolution. A misunderstanding of the existing logic led to screenshot dimensions becoming dependent on the host render window size.

This changes the behavior to match how it was prior to ART at 1x, with screenshots now always being the title's framebuffer dimensions scaled by the resolution scaling factor.
