[shader_recompiler] simplify decoder table logic and let compiler do tables for us (#2915)

The compiler is very smart, I trust the compiler to make a proper decoder selector rather than rolling our own.

Probably mostly benefitted on PGO builds.

Directly affects cache recompilation times (test with pipeline shaders OFF to force shaders to rebuild :)

Also restores CCTLT so we have the full ISA (or do we? Is ISBEWR missing? - someone should run fuzzing :)
