Map/Set: Introduce QV4::ESTable
This removes the duplication of code between Map and Set by placing it
in a shared location, and will hopefully be a touch more efficient than
using ArrayObject.
In a followup patch, it will get faster, too.
Note: As a bonus, this also fixed a few more test failures: forEach
wasn't handling the object being changed during iteration.
Task-number: QTBUG-68545
