This doesn't fully separate v8_inspector from
core, but it does lay the path.
The next steps to removing v8_inspector is to
remove all the # FIXME: Remove lines in the
deps section of v8_inspector/BUILD.gn.
gn check out/Debug v8_inspector
will tell us if we've successfully removed
all the dependencies.
It's unclear if we want to remove the wtf
dependency, but definitely all of the engine/core
dependencies should be removed and presumably
replaced with abstract interfaces which can be provided
to v8_inspector by its host.
Given the size of this patch (and that it's largely
mechanical) I plan to TBR it.
Most of this was done with tools/git/move_source_file.py
