Downgrade to V8 8.6.334 again (#447)

After the upgrade some Deno tests started crashing somewhere deep inside
V8, and the cause of these crashes is unclear.

This reverts the following commits:
* 12334ffe Upgrade gn to 6f13aaac; make BUILD.gn compatible with it (#443)
* f53f10d4 Upgrade V8 to 8.7.25 (#443)
