Update SPIRV-Headers, add cache control operand kinds (#5406) 
* Update SPIRV-Headers, add cache control operand kinds

Adds SPV_OPERAND_TYPE_LOAD_CACHE_CONTROL
and  SPV_OPERAND_TYPE_STORE_CACHE_CONTROL,
from SPV_INTEL_cache_controls

Fixes: #5404

* Update tests: remove Kernel from constant sampler enum dependencies

This corresponds to header change
