Subject: [PATCH] Posts, Post Types: Add a new filter for query arguments in
 `get_pages`.

In [55569] `get_pages` was converted to use `WP_Query` internally. But for plugins that were extending the `get_pages` filters and filter `WP_Query` query arguments, this could result in a conflict. Add a filter `get_pages_query_args` to allow developers to change arguments passed to `WP_Query` but also have the context of the original arguments passed to the `get_pages` function.

This change also expands test coverage of `get_pages` to ensure no breakages in the future.

Props spacedmonkey, westonruter, costdev, flixos90, kenwins, marianne38.
See #12821.
