Fix interface property hooks satisfied by plain typed properties (#7311)

[PurHur]

Summary

• Plain typed properties on implementing classes now satisfy PHP 8.4 interface { get; } / { get; set; } obligations (zend_property_hooks.c parity)
• inheritInterfacePropertyHooks / inheritParentPropertyHooks strip abstract/virtual hook metadata when a backing field implements the obligation
• Compile-time (InterfaceImplementationCheck) and runtime (AbstractPropertyHookCheck) treat declared backing fields as implicit get/set providers

Closes #7311

php-src reference

• Zend/zend_compile.c — interface property hook validation
• Zend/zend_property_hooks.c — backing-field satisfaction
