Revert "heap: Maintain live bytes counter during marking instead of sweeping"

This reverts commit 5980e50716016c7eab8e3ef3c1fb747e6ac0491f.

Reason for revert: Crashes on webgl bots.

Original change's description:
> heap: Maintain live bytes counter during marking instead of sweeping
> 
> Increase live byte counter on transitioning an object from unmarked to marked
> state. This results in an accurate live byte counter after marking and even
> before sweeping is started.
> 
> In future, this values is communicated to V8 to allow computing a global limit
> indicating when the next GC should be started.
> 
> Performance-wise, this only shifts the accounting work from the sweeper to the
> marker. Both still run on the main thread.
