408d89041e Reland "Add external backing store JS test" 
Allow mocking the limits for ArrayBuffer allocation to simulate operating
system OOM.

Fixes:
- Ensure OS limit > hard limit for external memory. This is necessary as
  any processing below the hard limit is opportunistic. E.g. a running
  sweeper may stall the current marking (GC) round.
- Immediately process AB allocations when under memory pressure. Otherwise,
  the allocations may be stuck in a stalled task. Freeing them upon
  adding them to the collector still enables parallelism if possible.

This reverts commit f3ad6cdb9c.
