Refactor embedder interface for conservative GC
...
Now users don't have to #ifdef on conservative vs precise tracing; it's
just a generic embedder concern.

Add conservative heap tracing (not just roots)
...
Also accelerate mark_space_live_object_granules.

Pass heap to tracer functions
...
This will allow conservative intra-heap edges. Hopefully no overhead?

Add conservative stack capture
...
This isn't really wired up yet anywhere, but add a precursor to
conservative stack scanning.

Fix race condition in computation of mark-while-stopping
...
Choose the ragged stop strategy when the GC kind is determined, so that
we do so with respect to a single measurement of pending unavailable
bytes.
Also remove assert in heap_should_mark_while_stopping, as it can be
called after stopping too, when evacuation is enabled.

Rework pinning, prepare for conservative tracing
...
We don't need a pin bit: we just need to mark pinned objects before
evacuation starts. This way we can remove the stopping / marking race
so that we can always mark while stopping.
