content: Add asyncCollectGarbage to GCController

Adds an async GC call to GCController which is used from asyncGC() during layout
tests.

Currently the async GC calls a regular V8 GC which schedules a precise Oilpan GC
as followup. In a unified GC world a V8 GC runs both, V8's GC and Oilpan, with
the difference that it has to conservatively scan the stack as Oilpan is not run
from the event loop. This is fixed by posting a task and calling a V8 GC
indicating that there's no relevant stack present.
