* Add support for the SupportedOSPlatformVersion MSBuild property, and write
it to the Info.plist for the corresponding minimum OS version.
* If there are any minimum OS version in the Info.plist, we'll now show an
error if it doesn't match SupportedOSPlatformVersion.
This unfortunately means that if there's any minimum OS version in any
Info.plist, then that will most likely have to be moved to the
SupportedOSPlatformVersion property (or removed entirely if that's the right
choice), since it's unlikely to match the default value for
SupportedOSPlatformVersion. However, this was deemed to be the best option for
the future (it's a one-time pain during migration).
Also add new tests, update existing tests, and update the templates.

Context: https://github.com/dotnet/maui/pull/807
When implementing a new `@(MauiSplashScreen)` feature for .NET MAUI, I
found out that Catalyst doesn't have support for splash screens.
I even tested this in Xcode:
* Create a new Objective-C iOS app
* Make `LaunchScreen.storyboard` red and `Main.storyboard` green.
* Check the new `macOS` checkbox in project settings to enable
Catalyst and be a multiplatform app.
I see red, then green on iOS but only green on macOS. I think Catalyst
completely ignores `UILaunchStoryboardName`.
This removes splash screens from the `dotnet new maccatalyst` template
as well as the `MyCatalystApp` sample project.
Also
* Fix the Mac Catalyst sample to use the correct contents.json and images sizes
for Mac Catalyst app icons.
* Fix the contents.json and image sizes for the Mac Catalyst test project as well.
* Add unit test for Mac Catalyst that ensures that Assets.car is in the final app.
