gtkscrolledwindow: Drop gtk_scrolled_window_set_capture_button_press()

Browse Source 
This API is kinda stuck in the GdkEvent days, we now negotiate ownership
of the input sequence via GtkGestures. Remove it as it reflects a way to
work that was not exactly accurate and it will turn plainly wrong soon.

/**
* gtk_scrolled_window_set_capture_button_press:
* @scrolled_window: a #GtkScrolledWindow
* @capture_button_press: %TRUE to capture button presses
*
* Changes the behaviour of @scrolled_window with regard to the initial
* event that possibly starts kinetic scrolling. When @capture_button_press
* is set to %TRUE, the event is captured by the scrolled window, and
* then later replayed if it is meant to go to the child widget.
*
* This should be enabled if any child widgets perform non-reversible
* actions on button press events. If they don't, it might be better to
* set @capture_button_press to %FALSE.
*
* This setting only has an effect if kinetic scrolling is enabled.
