  Log Message:
  -----------
  [SPIR-V] Add SPV_INTEL_bfloat16_arithmetic for Opencl.std instructions with bfloat16 type (#205128)

For `OpExtInst`, add check for bfloat16 type when it's an OpenCL.std
extended instruction, and add requirements for
SPV_INTEL_bfloat16_arithmetic if so.

Add such check and extension requirement since OpenCL.std extended
instruction set can operate on IEEE-754 FP types only, as per the
revision from [OpenCL.std
spec](https://registry.khronos.org/SPIR-V/specs/unified1/OpenCL.ExtendedInstructionSet.100.html#_changes_from_version_1_0_revision_8)
