[ci] Use new DevDiv/android-platform-support repo

[pjcollins]

Bumps external components to https://devdiv.visualstudio.com/DevDiv/_git/android-platform-support/commit/cdef164e7eef35128f74fa1f3ecbd7a878953a43

A new android-platform-support Azure Repo has been created in the DevDiv
project containing library code from the xamarin/androidtools,
xamarin/monodroid, and xamarin/android-sdk-installer repos.

The build has been updated to build and package all required closed
source components from the new Azure Repo.

@pjcollins we are going to need to build the fast dev tooling somehow also. I don't think they are referenced from the debugging project.

@pjcollins we are going to need to build the fast dev tooling somehow also. I don't think they are referenced from the debugging project.

As part of make jenkins we run dotnet build -t:BuildExternal Xamarin.Android.sln -- this command will still build the monodroid.proj file which has been brought forward into the new repo here - https://devdiv.visualstudio.com/DevDiv/_git/android-platform-support?path=/build-tools/monodroid.proj

This should continue to build the fastdev tools and ensure that Xamarin.Android.Build.Debugging.Tasks has the correct assembly version, but please double check my work here and make sure this all looks right!

I tried this branch, -t:Prepare worked, but then:

> .\dotnet-local.cmd build .\Xamarin.Android.sln -t:BuildExternal
Restore complete (1.5s)
  Xamarin.Android failed with 1 error(s) (0.0s)
    D:\src\xamarin-android\build-tools\scripts\DotNet.targets(12,5): error MSB6003:
      The specified task executable "cmd.exe" could not be run. System.IO.DirectoryNotFoundException: The working directory "D:\src\xamarin-android\build-tools\scripts\..\..\external\android-platform-support\build-tools" does not exist.

         at Microsoft.Build.Tasks.Exec.ExecuteTool(String pathToTool, String responseFileCommands, String commandLineCommands)
         at Microsoft.Build.Utilities.ToolTask.Execute()

What step should clone android-platform-support?

On windows I believe the PrepareExternal target should clone/update to the right ref, and on macos make prepare-external-git-dependencies should set up the source.

I think it's working for me now, -t:PrepareExternal popped up a login box:

I tested locally and things seemed to be working for me.

I reran some of the lanes that failed/timed out.
