vkd3d-shader/hlsl: Parse the shader 'compile' syntax.

Browse Source 
The hlsl_ir_compile node is introduced to represent the "compile"
syntax, and later the CompileShader() and ConstructGSWithSO()
constructs.

It basically represents a function call that remembers its arguments
using hlsl_srcs and keeps its own instruction block, which is discarded
when working on non-effect shaders.

For shader compilations it can be asserted that args_count is 1, and
that this argument (and the last node in hlsl_ir_effect_call.instrs)
is a regular hlsl_ir_call pointing to the declaration of the function
to be compiled.
