Posts, Post Types: Speed cached get_pages() calls.

Browse Source 
This improves performance for sites with persistent cache backend having a lot of pages requested via the `get_pages() function, by taking advantage of `wp_cache_get_multiple()` instead of fetching each individual page from the backend cache server one by one.

It also matches the behaviour of `get_pages()` when the pages are retrieved from the database.

Props david.binda, hellofromTonya.
