[browser] Trigger relink on EmccMaximumHeapSize change (#105027)

* Edit test + trigger relink.

* Remove logging to speed up the test + decrease loop runs to prevent "Browser has been disconnected" error.

* Feedback - properties are not bool-only anymore.

* Fix: workload needed when heap size set.
