Deprecate unbinding of $this of non-static methods

Static calls to non-static methods have been fully deprecated in
PHP 7.0 as part of https://wiki.php.net/rfc/reclassify_e_strict.

A combination of ReflectionMethod::getClosure() ("fake closures")
and Closure::bindTo() etc can be used to achieve the same behavior.
This commit ensures that a deprecation notice will be thrown also
in this case.

4. Deprecated Functionality
========================================
- Core:
. Unbinding $this of a non-static method through a combination of
ReflectionMethod::getClosure() and closure rebinding is deprecated. Doing
so is equivalent to calling a non-static method statically, which has been
deprecated since PHP 7.0.
