  [libclc] Move sign to the CLC builtins library (#115699)

This commit moves the sign builtin's implementation to the CLC library.
It simultaneously optimizes it (for vector types) by removing
control-flow from the implementation.

The __CLC_INTERNAL preprocessor definition has been repurposed (without
the leading underscores) to be passed when building the internal CLC
library. It was only used in one other place to guard an extra maths
preprocessor definition, which we can do unconditionally.
