gallium: replace PIPE_SHADER_CAP_INDIRECT_INPUT/OUTPUT_ADDR with NIR options

Browse Source 
This is a prerequisite for enabling nir_opt_varyings for all gallium
drivers.

nir_lower_io_passes (called by the GLSL linker) only uses NIR options
to lower indirect IO access before lowering IO and calling
nir_opt_varyings.

Most drivers report full support for indirect IO and lower it themselves,
which prevents compaction of lowered indirectly accessed varyings because
nir_opt_varyings doesn't touch indirect varyings.
