Revert new logic around FLAG_ALT_FOCUSABLE_IM

This broke several apps because it means certain NON_FOCUSABLE windows
are now layered wrong w.r.t the IME, and also no longer get IME insets.

Originally, this was introduced because the IME target was used to
compute which window gets control, but this is now computed based on
the window actually connecting to the IME as reported per IMMS.
