Uno Support for Windows.System APIs

`Launcher`

`LaunchUriAsync`

This API is supported on iOS, Android, WASM and macOS.

On iOS, Android and macOS the ms-settings: special URI is supported.

In case of iOS, any such URI opens the main page of system settings (there is no settings deep-linking available on iOS).

In case of Android, we support the following nested URIs.

Exceptions

When uri argument is null, NullReferenceException is thrown. Note this differs from UWP where AccessViolationException is thrown.
When the method is called from non-UI thread InvalidOperationException is thrown.

Exceptions are in line with UWP.

`QueryUriSupportAsync`

This API is supported on iOS, Android and macOS, and the implementation does not respect the LaunchQuerySupportType parameter yet. It also reports the aforementioned special ms-settings URIs on Android and iOS as supported.

Exceptions

When uri argument is null, NullReferenceException is thrown. Note this differs from UWP where a plain Exception with HRESULT is thrown.

Exceptions are in line with UWP.
