Android framework version

Affected platform version

.NET 10

Description

Xamarin.Android.PCLSupport.targets/props was only ever used/imported in Xamarin.Android and is not used in .NET 6+ projects.

Remove these files and all references to it.

As a part of this work, look for other MSBuild targets/props files that are not shipped (in build-tools\installers\create-installers.targets). List these and remove them as well.

Do not add empty blank lines to the diff.
