Caio Oliveira fe908ffefa glsl: Implement use_scoped_barrier option for lowering memory barriers
When the option is enabled, lower memory barriers to the
unified nir_intrinsic_scoped_barrier.

The translation of the following is based on
https://www.khronos.org/registry/OpenGL/extensions/ARB/ARB_gl_spirv.txt

- memoryBarrier()
- memoryBarrierBuffer()
- memoryBarrierImage()
- memoryBarrierShared()
- groupMemoryBarrier()

Also use scoped barrier for the memory counterparts of the GLSL
(control) barrier() when the option is enabled.  The execution
part of a (control) barrier() remains using the old intrinsic.

For memoryBarrierAtomicCounter() there's no corresponding
nir_var_atomic_counter mode. Since atomic counters are lowered
to SSBOs, use the nir_var_mem_ssbo mode in the scoped barrier
instead.
