Implement missing functionality of AudioBufferSourceNode
<!-- Please describe your changes on the following line: -->
This is a tiny PR to support [Media #293](https://github.com/servo/media/pull/293). Last time I ran WPT there was only one failing AudioBufferSourceNode test (which I will debug later this week). Once I rebased, however, I started getting unrelated servo-media build failures:
```
error[E0599]: no method named `shutdown_audio_context` found for type `std::sync::Arc<servo_media::ServoMedia>` in the current scope
--> components/script/dom/baseaudiocontext.rs:566:14
error[E0599]: no method named `shutdown_player` found for type `std::sync::Arc<servo_media::ServoMedia>` in the current scope
--> components/script/dom/htmlmediaelement.rs:1866:18
```
I wanted to get this PR up so https://github.com/servo/media/pull/293 can be tested. When the unrelated build failures are fixed, I will run `./mach update-wpt` and update this PR.

Added support to download nuget and added python code to automate the…
… x64 and arm64 mach build -r/-d --uwp build process.
<!-- Please describe your changes on the following line: -->
Modified/added python code to:
1. Download nuget which is required for building support\HoloLens
2. added python code to perform a nuget install/restore ServoApp.sln which causes the Angle libraries to be installed so that mach build will succeed.
3. added python code to perform a MsBuild of the support\HoloLens\ServoApp.sln solution so that mach build will build ServoApp and create a ServoApp .appx install file.
Note: The Msbuild path must be present otherwise the msbuild command will fail.

This makes some tests regarding clearing rects pass. Otherwise the rect
wouldn't get cleared properly and it'd keep its original color but get
an alpha of 0
I tried to mimic the azure implementation but raqote doesn't have a
concept of horizontal or vertical repeat so this might be
wrong/incomplete but this is the last function needed to finally have
some tests pass
