[macOS] Switch android tools installation to use cmdline-tools' sdkmanager (#3686)

* Switch android installation to use cmdline-tools
* Switch android-toolsets and xamarin-android-ndk to use new sdkmanager
* Remove cmdline-tools installation from toolset as it's installed
* Remove redundant steps with warning prevention
* Remove hardcoded licenses as they are accepted during the installation
* Add tests to check that both sdkmanagers are available
* Simplify Get-AndroidInstalledPackages function to use list_installed

* Change regex pattern to output the group
* Currently the function returns 4. instead of 4.0, this change fixes it
