This function is equivalent to the linker.cpp
build_program_resource_list() but will extract the resources from NIR
shaders instead.
For now, only uniforms and program inputs are implemented.
v2: move from compiler/nir to compiler/glsl (Timothy Arceri)
v3: remove support for inputs, that is still WIP (spotted by Timothy
Arceri)
