patches: fix C-n/C-p VoiceOver regression - exclude isCtrlNP from re-anchor

When Emacs moves the cursor (emacsMovedCursor=YES), we post
FocusedUIElementChanged on the NSWindow to re-anchor VoiceOver's
browse cursor.  For C-n/C-p this notification races with
AXSelectedTextChanged(granularity=line) and causes VoiceOver to
drop the line-read speech.

Arrow key movement works because VoiceOver intercepts those as AX
selection changes (setAccessibilitySelectedTextRange:), making
voiceoverSetPoint=YES and emacsMovedCursor=NO, so no
FocusedUIElementChanged is posted.

Fix: skip FocusedUIElementChanged for sequential C-n/C-p moves
(isCtrlNP).  AXSelectedTextChanged with direction=next/previous +
granularity=line is sufficient for VoiceOver to read the new line.
FocusedUIElementChanged is only needed for discontiguous jumps
(]], M-<, isearch, xref etc.) where VoiceOver must re-anchor.

Also merge duplicate comment blocks and fix two compile errors
from a64d24c that Martin caught during testing.
