nir: switch indirect IO load lowering to nir_lower_io_indirect_loads for GLSL
This reduces GLSL compile times with the gallium noop driver by 0.6%.
This might decrease register usage and do less code reordering because
nir_lower_io_vars_to_temporaries is no longer called for inputs, which
moved most input loads to the top.
radeonsi+ACO shader-db results are noise.
More uniforms are identified as inlinable.
