Fix OpImageRead result type when compiling HLSL - Per the Vulkan spec, OpImageRead must return a 4-component vector always. When compiling HLSL, loads from a RWTexture of a template type with < 4 components would incorrectly generate an OpImageRead with a < 4 component result, resulting in validation errors. - This was previously fixed for OpImageFetch in commit 4425f24; this commit does the same thing for OpImageRead. - Added associated tests and expanded existing image fetch tests to check all the different types of textures, in both float and int incarnations, for completeness. - Update other HLSL tests involving OpImageRead
