Refactor attribute handling on the shader generator (#4565)
* Refactor attribute handling on the shader generator * Implement gl_ViewportMask[] * Add back the Intel FrontFacing bug workaround * Fix GLSL transform feedback outputs mistmatch with fragment stage * Shader cache version bump * Fix geometry shader recognition * PR feedback * Delete GetOperandDef and GetOperandUse * Remove replacements that are no longer needed on GLSL compilation on Vulkan * Fix incorrect load for per-patch outputs * Fix build
