Michael Lippautz 55d00c95b0 [heap] Fix ArrayBufferTracker accessing already swept byte length 
The tracker needs to maintain the byte length as there is no order guarantee
when sweeping pages and the byte length may be a HeapNumber that is stored on a
different page.

The abstraction for ArrayBuffers is left untouched. We distinguish between the
following cases:
1. Regular AB (backing_store and bye_length should be used)
2. AB allocated using kReservation but not part of wasm
3. AB allocated using kReservation and part of wasm

In practice, 2. does not exist, but we still maintain "allocation_base" and
"allocation_length" which fall back to backing_store and byte_length in this
case. The problematic part is that they look like innocent getters on the
object but actually refer to different data structures or on-heap objects.

Since 2. does not exist, and 3. looks up the bounds in its own tracker, it is
fine for ArrayBufferTracker to pass backing_store and tracked byte_length.
