spirv/nir: handle memory access qualifiers for SSBO loads/stores

v2: - change how the access qualifiers are accumulated
v3: - duplicate members in struct_member_decoration_cb()
    - handle access qualifiers on variables
    - remove access qualifiers handling in _vtn_variable_load_store()
    - fix setting access qualifiers on type->array_element
