[Model Element] Limit the number of models that can load in parallel to lower
peak memory footprint
rdar://153908401
https://bugs.webkit.org/show_bug.cgi?id=295257
Reviewed by Mike Wyrzykowski.
Limit the number of models that can load in parallel to 3 by default to lower
the peak footprint. When a model load is scheduled, it's appended to a Deque
and RKUSDModelLoadScheduler::loadNextModel() is called to take a loader
off that Deque to load if the number of in-progress loaders is within the limit.
RKUSDModelLoadScheduler::loadNextModel() is called whenever a loader has
finished to see if another loader can start loading.
* LayoutTests/model-element/model-element-multiple-loads-expected.txt: Added.
* LayoutTests/model-element/model-element-multiple-loads.html: Added.
Test to make sure many models created at the same time can all finish
loading in the end.
