Add a new specification to select GRF size that will be implemented using a more modern mechanism to communicate the user's specification. It is not yet implemented.

Signed-off-by: Nick Sarnie <nick.sarnie@intel.com>
Applications should generally rely on the compiler's default selection unless
profiling demonstrates a benefit from specifying a different GRF size.

This extension is similar to link:../experimental/sycl_ext_intel_grf_size.asciidoc[sycl_ext_intel_grf_size]

Full disclosure, I copy and pasted the grf_size spec, did a rename from grf_size to maximum_registers, updated the copyright, updated the 'Backend support status' section, and added this line about differences with grf_size.

If there is some other expected difference between the specs please let me know.
