So they are not exposed through the introspection API.
It is worth to note that the number of hidden uniforms of GLSL linking
vs SPIR-V linking would be somewhat different due the differen order
of the nir lowerings/optimizations.
For example: gl_FbWposYTransform. This is introduced as part of
nir_lower_wpos_ytransform. On GLSL that is executed after the IR-based
linking. So that means that on GLSL the UniformStorage will not
include this uniform. With the SPIR-V linking, that uniform is already
present, but marked as hidden. So it will be included on the
UniformStorage, but as hidden.
One alternative would create a special how_declared for that case, but
seemed an overkill. Using hidden should be ok as far as it is used
properly.

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)
