In the future, GeckoAppShell will only be part of the service process library, and will not be part of the app process library. Therefore, we should minimize GeckoAppShell usage in any GeckoView code that will likely end up in the app process library. In particular, AndroidGamepadManager and Clipboard are made to accept Context as arguments, instead of using GeckoAppShell.getApplicationContext() for getting the Context.
