Separate Closure::bind() implementations

Closure::bind() and Closure::bindTo() are currently reported as aliases in stubs because they have a single implementation. They are not aliases in fact though, they just use zend_parse_method_parameters() cleverly.

Thus, let's separate their implementation so that we don't have to alias Closure::bindTo() anymore. This will also have the advantage that the two ZPP implementations become more clear.

Closes GH-6169
