GS/HW: Backport some tex is fb shaders to dx and opengl.

Fixes an issue with texture copies didn't work properly on tex is fb draw:
Fixes Hitman Blood Money on minimum blend.

DX can't do partial depth copy so do a shader based copy which works.
Fixes a bunch of games that couldn't do partial depth copy on dx.
