  [libclc] Move frexp to CLC library; optimize half vecs (#127836)

This commit moves the frexp builtin to the CLC library.

It simultaneously optimizes the code generated for half vectors, which
was previously scalarizing and casting up to float. With this commit it
still casts up to float, but keeps it in the vector form.
