deps: ensure V8 5.4 ABI compatibility

V8 5.5 is not ABI-compatible with 5.4. Make the necessary changes to V8's header files so that native addons compiled against a previous version of node can still be loaded.. * Remove new fields from {Indexed|Named}PropertyHandlerConfiguration. * Revert "[tracing] Support ConvertableToTraceFormat argument type." * This reverts commit 4810f41a521227ccab4f231aa4a439d790428953 from V8. * Remove tests for getOwnPropertyDescriptor and defineProperty interceptors.
