PR Type

What kind of change does this PR introduce?

• Feature
• Refactoring (no functional changes, no API changes)
• Build or CI related changes

What is the current behavior?

NuGet package references are spread across project files. It is difficult to track versions and upgrade them properly.

What is the new behavior?

Enables NuGet's upcoming feature to manage package versions centrally using Directory.Packages.props with the following item spec to store a package version.

  <ItemGroup>
    <PackageVersion Include="Vendor.Awesome.Package" Version="11.0.0" />
  </ItemGroup>

The build failed, since, there's an issue with MSBuild.Sdk.Extras UWP implicit package reference. Thus, I'll be using a fork of the Extras SDK with fixes for this issue. I'll later patch the Extras SDK itself with those fixes!

I have extracted unrelated refactoring into its own PR: #4234; I'll rebase this on latest once the PR is merged.
