Also remove now-dead code that rustc warns about.
It turns out that we lost support for some of our custom URL schemes; I intend
to reimplement them, but I believe this will be significantly easier to do
once the legacy code is out of the way.
Add redirect_mode to RequestInit
This adds support for non-follow redirect modes for `RequestInit`.

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.
The spec removed it. Check the scheme instead, data is always same origin now,
except for workers.
This also updates the comments to make step numbers match the spec.
Closes#13362
