options, x11+cocoa: add option --cursor-autohide-delay

Add option --cursor-autohide-delay to control the number of milliseconds
with no user interaction before the mouse cursor is hidden.

There are two negative values with useful special meanings:
* A value of -1 prevents the cursor from hiding (useful for users
  with multiple displays).
* A value of -2 prevents the cursor from showing upon activity.

The default is 1 second to keep the behaviour consistent with the
past X11 backend implementation.

Remove the vo_mouse_autohide field as it was always true.
