  [libclc] Move mad_sat to CLC; optimize for vector types (#125517)

This commit moves the mad_sat builtin to the CLC library.

It also optimizes it for vector types by avoiding scalarization. To help
do this it transforms the previous control-flow code into vector select
code. This has also been done for the scalar versions for simplicity.
