Subject: chore: add gin::wrappable wrapperinfo crash key
This patch adds an additional crash key for gin::Wrappable, to help
debug a crash that is occurring during garbage collection in SecondWeakCallback.
The crash seems to be due to a class that is holding a reference to
gin::Wrappable even after being deleted. This added crash key compares
the soon-to-be-deleted WrapperInfo with known WrapperInfo components to
help determine where the crash originated from.
This patch should not be upstreamed, and can be removed in Electron 15 and
beyond once we identify the cause of the crash.
