Calling this function will result in the [signal@TabView::close-page] signal
being emitted for @page. Closing the page can then be confirmed or
denied via [method@TabView.close_page_finish].
If the page is waiting for a [method@TabView.close_page_finish] call, this
function will do nothing.
The default handler for [signal@TabView::close-page] will immediately confirm
closing the page if it's non-pinned, or reject it if it's pinned. This
behavior can be changed by registering your own handler for that signal.
If @page was selected, another page will be selected instead:
If the [property@TabPage:parent] value is NULL, the next page will be
selected when possible, or if the page was already last, the previous page
will be selected instead.
If it's not NULL, the previous page will be selected if it's a descendant
(possibly indirect) of the parent. If both the previous page and the parent
are pinned, the parent will be selected instead.
