goldislead a635ac64f5 [GPU] Scaled resolve readback through downscale CS
Implements readback for resolution-scaled resolves in both D3D12 & Vulkan backends, mostly mirroring Xenia Edge's approach, with a few small adjustments.

The scaled resolve buffer stores each texel as a group aligned scale_x by scale_y block. A small CS now reverses that packing per 32x32 tile and writes 1x. So far, this is Edge's approach verbatim. This slightly diverges from Edge since now the source window is bound at the written extent, not the texture base & the tail after the last whole tile is no longer copied.

Dest format and texel size are the same ResolveInfo the written extent was calculated with rather than rereading RB_COPY_DEST_INFO, which probably matters for depth resolves where the register holds k_8. 128bpp dests, extents that aren't group-aligned, and extents outside the scaled range skip readback.
