I have verified that desktop and emulator UWP builds work with this set of DLLs.

It's impossible to conditionally use a crate based only on cargo features, so
temporarily disable the backend on all Windows builds while we sort out how
to get the UWP builds working again.
Make Windows arm64 easy
* Add a ServoApp project configuration
* Add a `--win-arm64` build flag (now `python mach build -r --win-arm64 --uwp`)
* Automatically set up GStreamer LIB environment
* Yell if the cross-compilation environment isn't set up correctly
* Automatically find the Visual C++ installation for DLL packaging, rather than relying on an environment variable

Support WebAudio on Windows
These changes improve the GStreamer experience on Windows in several ways:
* we package the set of plugins and their dependencies that Servo requires for media support
* we explicitly load those plugins when starting the media engine rather than relying on an existing gstreamer installation
These changes do not affect the experience on non-Windows platforms, but the path is clear to do so in order to fix problems like #23519. With these changes I can successfully hear a tone when loading https://joshmatthews.net/osc.html in both a desktop build and a UWP build.

updated rustup requirement
<!-- Please describe your changes on the following line: -->
Rustup changed their argparsing, which resulted in `./mach test-unit --nocapture` not working. Servo now requires a higher rustup version to ensure that mach commands work

Add UWP port - bis
This is #23658 with some fixes:
- removed nspr from DLL dependencies (was breaking VS build)
- exclude symbols from header file (was breaking VS build)
- rebased
Before merging:
- please check the rebased commit that introduces the `--uwp` option (things moved around since 7c85dc09b5)
- should we wait until the WR fix lands upstream?

Not all cargo subcommands take `--manifest-path`.
Use plain `cargo` instead (rustup reads the `rust-toolchain` file)
or consider adding new mach sub-commands.
build: Cleanup some path-munging code.
I was looking at this today, and this seems better than the pre-existing code,
generally pre-pending to these paths isn't great...
