rb_ext_ractor_safe() to declare ractor-safe ext
C extensions can violate the ractor-safety, so only ractor-safe C extensions (C methods) can run on non-main ractors. rb_ext_ractor_safe(true) declares that the successive defined methods are ractor-safe. Otherwiwze, defined methods checked they are invoked in main ractor and raise an error if invoked at non-main ractors. [Feature #17307]
