WebBluetooth Test API and tests
<!-- Please describe your changes on the following line: -->
This patch depends on the [devices mock device support PR](https://github.com/servo/devices/pull/17).
After it lands, the Cargo files can be updated.
1. Adjust to the changes in [devices mock device support PR](https://github.com/servo/devices/pull/17).
2. WebBluetooth Test API implementation. Based on : https://webbluetoothcg.github.io/web-bluetooth/tests.html
3. Wpt tests for the already landed WebBluetooth functions.

Layers were a feature of the legacy drawing path. If we re-add them at
some point, it probably makes more sense to make them a product of
display list inspection.
This change also remove a bunch of dead painting code.
Support taking screenshots when a webdriver server is active.
Improve the experience of using webdriver to take screenshots of Servo. When a screenshot can't be obtained immediately, increase the delay before trying again from 2ms to 1s.

This removes paint threads, rust-layers dependency, and changes
optional webrender types to be required.
The use_webrender option has been removed, however I've left
the "-w" command line option in place so that wpt
runner can continue to pass that. Once it's removed from there
we can also remove the -w option.
Once this stage is complete, it should be fine to change the
display list building code to generate webrender display
lists directly and avoid the conversion step.
SubpageId was originally introduced in 2013 to help iframes keep track of
their associated (children) pipelines. However, since each pipeline
already has a PipelineId, and those are unique, those are sufficient
to keep track of children.
Consistently use the name 'pipeline_id' to refer to a function that
returns an (optional) PipelineId.
This was prompted by discovering both fn pipeline and fn pipeline_id
doing the same job in htmliframeelement.rs.
Note that there is fn pipeline in components/compositing/compositor.rs,
but that actually returns an Option<&CompositionPipeline>, not any kind
of PipelineId.
a script query.
This will, rather unfortunately, mean that we might repaint two times if we've
deferred a paint, then get an out-of-band reflow. Still seemed better than not
suppressing paints at all.
Fixes#13131
