Make convert_to_*_ex simple aliases of convert_to_*

Historically, the _ex variants separated the zval first, if a
conversion was necessary. This distinction no longer makes sense
since PHP 7.

The only difference that was still left is that _ex checked whether
the type is the same first, but the usage of these macros did not
actually distinguish on whether such an inlined check is valuable
or not in a given context.

Also drop the unused convert_to_explicit_type macros.
