The AndroidX packages that MAUI currently uses all support trimming, however some of their new dependencies did not, such as
Xamarin.Kotlin.StdLib. This caused a size regression on Android because these new libraries were not being trimmed.AndroidX dependencies have been updated with trimming support, and new packages have been released that update the dependency tree.
This PR updates MAUI to use these new AndroidX versions.
