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.

Remove uses of UsesNativeCallProxy and UsesGeckoThreadProxy, now that
they are not needed.
Remove cases where we had to invoke a call in a proxy, because the call
is now specified to be invoked directly in the WrapForJNI annotation,
without the need to go through the proxy.
For SmsManager and AlarmReceiver, we no longer need to manually dispatch
everything to the Gecko thread because that's now handled automatically.
Add native method calls to AndroidGamepadManager to replace the gamepad
events in GeckoEvent. Implement those calls in AndroidGamepad.cpp. The
jni/Refs.h change is necessary to fix a compile error when using
jni::BooleanArray.
