Resolve disagreements in accounting of tooltip positions on Android

* java/org/gnu/emacs/EmacsService.java (getLocationInWindow):
New function.

* java/org/gnu/emacs/EmacsWindow.java (translateCoordinates):
Derive "root window" position from the origin point of the
containing activity's window rather than that of the screen,
the two of which differ when "freeform mode" is enabled.
