Rename #updateInputMethodWindowStatus() to #setDismissImeOnBackKeyPressed()

This is a purely mechanical method renaming.  There should be no
behavior chagne.

To summarize,

  WindowManagerInternal#updateInputMethodWindowStatus()

should be renamed to

  WindowManagerInternal#setDismissImeOnBackKeyPressed()

and this CL actually does so with also removing unused parameters.

The method in question was originally added by me for the
true-IME-target-window project [1] at Bug 34628091 then updated to
propagate one more boolean value from InputMethodManagerService to
PhoneWindowManager to address a feature request from Wear team [2] at
Bug 33824860.

After that, we also introduced another method

   WindowManagerInternal#updateInputMethodTargetWindow()

for the true-IME-target-window project [3] and that's what we ended up
having relied on.  Given that #updateInputMethodWindowStatus() is used
only for Bug 33824860 to propagate "dismissImeOnBackKeyPressed"
parameter from IMMS to PhoneWindowManager, it'd make more sense to
rename its method name as well.
