Various UWP GStreamer improvements
There are a number of positive changes in these commits:
* we successfully load GStreamer plugins in ARM64 UWP builds
* we correctly link the ARM64 ANGLE libraries when appropriate
* it is no longer necessary to manually set the LIB environment variable on Windows
* we automatically download and link against UWP-friendly GStreamer binaries when building with `--uwp`
* the use of vcruntime140.dll, msvcp140.dll and api-ms-win-crt-runtime-l1-1-0.dll in the UWP application has been removed and the build does not repackage them
* the set of base supporting GStreamer DLLs has been expanded to allow the gstlibav plugin to load correctly

Support running WebGL in its own thread or on the main thread.
This is the final missing piece to support WebGL in ANGLE on Windows. ANGLE doesn't support multiple GL contexts on separate threads using the same underlying Direct3d device, so we need to process all GL operations for WebGL on the same thread as the compositor. These changes try to retain enough flexibility to support both approaches so we can get WebGL working on Windows ASAP.

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

- [x] create a struct JSContext(*mut jsapi::JSContext) type
- [x] implement Deref for this new type so it's easy to obtain the inner context pointer
- [x] add an unsafe from_ptr static method that returns a new instance of the type
- [x] start by changing various Argument uses in CodegenRust.py for python classes that inherit from CGAbstractMethod
- [x] convert the python code that interacts with CGClass (CGCallback, CGCallbackFunction, CGCallbackFunctionImpl, CGCallbackInterface) and any rust code that interacts with it
- [x] update CGDictionary and any rust code that interacts with it
- [x] make the code generator declare trait methods that accept the new type instead of *mut JSContext (CGInterfaceTrait)
- [x] modify GlobalScope::get_cx to return a SafeJSContext
