ES31: Translate compute shader HLSL system variables in compile time
This patch moves the implementation of translating compute shader
builtin variables from link time to compile time.
Unlike graphics shaders that require the information from other
shader stages, we actually have enough information to translate
compute shader builtin variables in compile time.
Many redundant codes in DynamicHLSL have been removed after this
refactor.
