deps: cherry-pick a8f6869 from upstream V8
Original commit message:
[debug] Fully implement Debug::ArchiveDebug and Debug::RestoreDebug.
I have a project that embeds V8 and uses a single `Isolate` from multiple
threads. The program runs just fine, but sometimes the inspector doesn't
stop on the correct line after stepping over a statement that switches
threads behind the scenes, even though the original thread is restored by
the time the next statement is executed.
After some digging, I discovered that the `Debug::ArchiveDebug` and
`Debug::RestoreDebug` methods, which should be responsible for
saving/restoring this `ThreadLocal` information when switching threads,
currently don't do anything.
This commit implements those methods using MemCopy, in the style of other
Archive/Restore methods in the V8 codebase.
