Auto merge of #23961 - angelortiz1007:servo-issue, r=jdm

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.
