Deprecate the "" operator, and isEqP

While a cool example of how to do string matching in constexpr space,
the set of verbs available to HTTP has been fixed for a very long time.

This was ported over to beast a while back, but we kept the API for....
mediocre reasons of backward compatibility.  Remove that, and delete the
now unused code.

Tested: Built and loaded on a Witherspoon. Validator passes.
