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.

Make reload button clear the network cache.
The developer workflow in FxR is frustrating right now because of bugs like https://github.com/servo/servo/issues/24385. To allow us to put out a new release soon that addresses this papercut, these changes make the reload button clear the network cache in FxR.

UWP: non random port for devtools, and support for custom UWP prefs
packages-prefs.json is now taken into account for libsimpleservo. Making it possible to have custom pref for the UWP builds, removing some weirdness in the way we handle preferences in the hololens code.
This also adds a new set of preferences to control the devtools server startup state, and make the port choice constant across sessions.

This is based on compiling with `RUSTFLAGS="-W unused_crate_dependencies"` (CC https://github.com/rust-lang/rust/pull/72342) in a recent Nightly (more so than used in the tree as of this writing, CC https://github.com/servo/servo/issues/26661 for work-arounds).
Only one crate is actually removed from the dependency graph, others are still dependended from other places.
