The constellation can now tell the memory reporter to report the memory
to a trace file when a page is loaded.
Additionally, we amend the memory reporter to allow a simple message
where it will report the memory to a tracing provider (at the moment
only OHOS/hitrace is supported but easy extension is possible).
I am not sure if this is the right approach or if the embedder should
decide to have the memory reporting done.
Testing: This does not change functionality of any of the rendering.
