Prior to this commit, `v8::NamedPropertyHandlerConfiguration` and `v8::IndexedPropertyHandlerConfiguration` did not expose the `definer` hook, or `flags`. This commit adds these options. In the process of doing this a couple of other changes were made: - Bitflag enum consts are now member consts of the related struct. This is done because PropertyHandlerFlags has conflicts with PropertyAttribute. - PropertyDescriptor gets all C++ introspection methods exposed to Rust. - NamedPropertyHandlerConfiguration callback types get rustdoc comments. - IndexedPropertyHandlerConfiguration callback types get rustdoc comments. - GenericNamedPropertySetterCallback gets a ReturnValue parameter, to signal trap passthrough.
