spirv: Handle PhysicalStorageBuffer in memory barriers

Browse Source 
PhysicalStorageBuffer is lowered to nir_var_mem_global, and
SPIR-V 1.5rev1 in section "3.25. Memory Semantics <id>" says

    UniformMemory

    Apply the memory-ordering constraints to StorageBuffer,
    PhysicalStorageBuffer, or Uniform Storage Class memory.
