v5.2.1 for Windows on Arm64 (unofficial)

Unofficial GitExtensions v5.2.1 build artifacts for Windows on Arm64 (WoA) platform, supplementing the official v5.2.1 release artifacts.

Here are the commands to build (applied to the release/v5.0 branch), executing on a WoA box:

> cd eng
> python set_version_to.py -v 5.2.1 -t 5.2.1_arm64
> cd ..
> dotnet build -c Release
> dotnet build .\src\native\build.proj -c Release /p:TargetPlatform=arm64
> dotnet publish -c Release /p:TargetPlatform=arm64

The last command would produce a .msi installer distribution, as well as a portable GitExtensions zip distribution for WoA, in the folder artifacts\Release\publish.
