This adds a new API function that can be customized by the embedder by providing a delegate that defines contexts to be measured and reports the results to JS. A memory measurement request is carried out as follows: 1) MeasureMemory(delegate) invocation enqueues a new request in MemoryMeasurement::received_ and schedules a delayed GC task. 2) At the start of the next GC (that is triggered either by the GC schedule or by the delayed task) each request in received_ moves to processing_. Per-context marking worklists are created for each native context that was selected by the delegates (using the ShouldMeasure predicate). 3) At the end of the GC the sizes of the native contexts are recorded for each request in processing_. The requests move to the done_ list and result reporting task is scheduled. 4) When the result reporting task runs it invokes the MeasurementComplete function of each delegate in done_.
