Stop lying about MissingMethodFlags.REQUEST_CURSOR_UPDATES
This is a follow up CL to my previous CL [1], which used
MissingMethodFlags mechanism [2] to let that API fail when the IME and
the target app are not running on the same display.
As discussed in Bug 194110780, however, there is a problem in the
MissingMethodFlags mechanism that it could have caused unexpected task
reordarings from the IME developer when sync InputConnection APIs
immediatelly fail without waiting for those tasks to be scheduled to
the target app then handled.
As a preparation to fully deprecate MissingMethodFlags, this CL
enables InputMethodManagerService to stop lying about
MissingMethodFlags.REQUEST_CURSOR_UPDATES
when the IME is rendered on a diffirent display than the target app.
Such check is now explicitly implemented in
RemoteInputConnectionImpl.
Other than that, there is no observable behavior change.
