  [libclc] Move step to the CLC library; add missing half variants (#140936)

The half variants were missing but are trivial to implement. There were
some incorrect mixed type overloads (step(float, double)) which aren't
in the OpenCL specification and so have been removed.

Like certain other builtins the CLC step function only deals with
identical types. The OpenCL layer is responsible for casting the scalar
argument to a vector.

This commit also trivially vectorizes the CLC function, generating
better bytecode.
