This adds a libFuzzer debug builder that only builds the V8 fuzzer
targets, which require debug builds to find the most useful bugs.
This is analogous to the existing release builder for high-end
targets.
For a short grace period, the V8 targets are enabled on the release
and debug builder. They'll be dropped from the release builder once
these builds are working and consumed on the Clusterfuzz side.
By only building V8 targets, this builder will be quite fast and
won't have a long cycle time.
