[build] Update package metadata (#9230)

Looking at the package explorer for recent .NET 9 preview 7 builds I
noticed that other packages do not include sha metadata in the
version element.

Compare the following by clicking "View Metadata source":

  * https://nuget.info/packages/Microsoft.Android.Runtime.35.android-arm/35.0.0-preview.7.41
    > <version>35.0.0-preview.7.41+sha.a9d10b4</version>
  * https://nuget.info/packages/Microsoft.NETCore.App.Runtime.Mono.android-arm/9.0.0-preview.7.24405.7
    > <version>9.0.0-preview.7.24405.7</version>
  * https://nuget.info/packages/Microsoft.Maui.Sdk/9.0.0-preview.7.24407.4
    > <version>9.0.0-preview.7.24407.4</version>

I believe the sha metadata was added when we were initially figuring
out a package versioning schema that would produce unique package
versions; however, our usage of commit distance in both preview and
stable versions should address this concern.

The sha metadata inclusion in the version element but not the `.nupkg`
name also causes conflicts with the latest version of the
[arcade publishing tooling][0] which expects these to be in sync.

The short hash in the metadata has been replaced by a `repository`
element which will contain the repo url and full commit hash:

	<repository type="git" url="https://github.com/dotnet/android" branch="refs/heads/dev/pjc/pack-repo-meta" commit="eb5455aaecd59ca979f184e7992624819e263315" />

The icon and other package metadata have been updated to better match
other .NET packages.

 ## Package Versioning Scheme

+This is the package version scheme: `OS-Major.OS-Minor.InternalRelease[-prereleaseX].CommitDistance`.
 
 * Major: The highest stable API level, such as 30. On Apple platforms, this is the major OS version.
