Perform preloading attempt on copied class
It is very hard to determine in advance whether class linking will
fail due to missing dependencies in variance checks (#7314 attempts
this). This patch takes an alternative approach where we try to
perform inheritance on a copy of the class (zend_lazy_class_load)
and then restore the original class if inheritance fails. The fatal
error in that case is recorded and thrown as a warning later.
Closes GH-7319.

Implement basic variance support
This is a minimal variance implementation: It does not support any
cyclic type dependencies. Additionally the preloading requirements
are much more restrictive than necessary. Hopefully we can relax
these in the future.
