Fixes: dotnet#6075 Fixes: dotnet#6076 Context: dotnet/macios#12173 We need to make two sets of changes for C# 10: 1. Support "global usings". Our .NET 6 templates should have no `using` statements at the top of `.cs` files. 2. Use `$(Nullable)` `enable` by default in project templates. To test this, our .NET 6 MSBuild tests use `Nullable=enable` by default and do no include `using` statements. I've made a new `MainActivity.cs` for our .NET 6 MSBuild tests. The "legacy" Xamarin.Android tests will use the original file.

So `AutoImport.props` should become: <ItemGroup Condition=" '$(TargetPlatformIdentifier)' == 'android' and ('$(ImplicitUsings)' == 'true' or '$(ImplicitUsings)' == 'enable') "> <Using Include="Android.App" /> <Using Include="Android.Widget" /> <Using Include="Android.OS.Bundle" Alias="Bundle" /> </ItemGroup> So these items are present at the time `.csproj` files are evaluated. Any templates will add: <Nullable>enable</Nullable> <ImplicitUsings>enable</ImplicitUsings> If users want to configure these settings, they can remove `$(ImplicitUsings)` from the `.csproj` completely or remove specific `@(Using)` items: <ItemGroup> <Using Remove="Android.App" /> </ItemGroup>
Also update our templates to remove any using statements for implicitly imported
namespaces.
Fixes #12084.
