GPU/HLE compat batch: fix crash classes from issue logs 40-87

Texture cache: page-accurate alias retirement with isolation (#84),
pool-reuse retirement for clean render targets and storage/sampled
aliases (#54, #62, #52, #70, #48), compressed video-out refresh from
raw guest backing (#71-#75), storage writeback and realigned storage
buffer bindings (#85).

Descriptors: 3D Standard4KB storage textures and MinLod meta on
write-only UAVs (#82, #40, #77, #63, #64), storage encoding for
DCC-tagged first-party T#s (#56, #87), cube depth targets (#43),
packed-float storage swizzles, BGRA-as-RGBA8-uint sampled views (#41).

Views are validated against eMutableFormat at creation to keep format
reinterpretation defined; layered RT views, NGS2 rack 0x4003, EOP
fallback writes, and null QueryMemoryProtection return EFAULT instead
of exiting. Structured-merge escape dispatch in the shader recompiler
(#67).
