Handle devtools clients disconnecting better
These changes fix many opportunities for the devtools server to panic if a client disconnects early. Now that it's easy to have multiple clients connected simultaneously, this also makes it easier for server code to distinguish between different clients and ensure that one client disconnecting doesn't affect another client that's still connected.

Revert webrender upgrade
These commits revert the webrender and font-related updates from #27207. This will unbreak our FxR nightly builds while we continue to investigate the underlying crash in ANGLE. Unfortunately it also returns us to the status quo of broken canvas text rendering on UWP, but there's no way to upgrade font-kit without any of the other crates because of the underlying freetype dependency changes that happened.
Fixes#27492.

UWP Crash reporter
This is supposed to address #27167 and #26523. Also fix#27435.
These changes are still WIP as I found a few bugs, it needs more testing and the actual code to upload is not implemented yet. But I'd like to get an early feedback.
First, panics are caught via `panic::set_hook` instead of `catch_unwind` allowing us to catch more panics.
We also now report panics reported via the `Embedder:Panic` message.
Once the panic is caught, if possible, we try to recover.
I haven't found a way to recover when the panic is caught is a non-GL thread. We need a generic way to throw from the UWP code, and even trying to add a UnhandledEvent handler doesn't appear to work.
Once a panic is caught (even if we can not recover) a crash-report file is created, including the backtrace, stdout, and the current url.
If the app did not crash at that point, or after a restart if it did, we check if the crash report file is present, and if so, we present a panel to the user to allow them to upload the report. At that point the user can also add details to the report.
