[GitHub] Update our new issue templates. (#1001)

We no longer need to ask if this is Classic Xamarin.Android or Android for .NET in the issue template.

Additionally, remove the PR template.  It's outdated (support libraries) and doesn't seem to provide any value, and none of our other repositories have one.
