bug 1209147 - make proxying of Accessible::TakeFocus() async r=davidb

Browse Source 
TakeFocus() ends up making sync calls to the parent process. That means if we
try to call it from a sync call to the child process we end up deadlocked.  The
easiest way to fix this is to make the message to the child process async.
