[perf] Skip ancestor reflection when no parent:: call to trim

[TomasVotruba]

RemoveArgumentFromDefaultParentCallRector subscribes to Class_. For every class that extends a parent it resolved the class reflection and walked getAncestors() - native reflection over the whole ancestor chain - before checking whether the class body even contains a parent:: call to trim. A subclass that never calls parent:: (the common case) paid for that ancestor lookup only to find nothing to do.

A cheap AST pre-scan (hasParentStaticCall) now bails before resolveClassReflection()/getAncestors() when no non-private, non-abstract method body holds a parent:: static call. It mirrors the guards the main loop already applies, so it never skips a class the rule would have changed.

Behavior unchanged - all 5 fixtures pass.

A standalone bench is included (bench/remove_argument_from_default_parent_call_bench.php), driving refactor() over 150 subclasses that extend a parent but never call parent::. CPU per call, averaged, two runs each:

	CPU us/call
before	2.66
after	0.87

~3x faster on that hot path. Run php bench/remove_argument_from_default_parent_call_bench.php on each branch to reproduce.
