[libclc][libspirv] Move degrees to CLC library (#16625)

This commit follows the general framework we want to achieve upstream;
we now have a new __clc_degrees builtin, which the OpenCL and SPIR-V
builtins both call for implementation.

This marks a change from having the OpenCL builtin call the SPIR-V
builtin for its implementation.
