  [OpenCL] Add decls for cl_intel_bfloat16_conversions (#150393)

These map to SPIR-V instructions, which are long supported by the llvm
SPIR-V target [1] and the llvm-spirv translator [2].

Intel's offline compiler (ocloc) and OpenCL implementation trivially
supports these, by having these same declarations [3] and relying on
llvm-spirv to map calls to them to their corresponding SPIR-V
instructions.
