 Improve global variable setting in `setup_postdata()`.

 `setup_postdata()` is responsible for setting a number of global variables
 that are used for post pagination (`$pages`, `$page`, `$nextpage`) and the
 generation of post excerpts (`$more`). These variables should be sensitive
 to
 the currently running instance of `WP_Query` - rather than the main query
 -
 so that these features work properly inside of secondary `WP_Query` loops.

 This changeset moves the logic of `setup_postdata()` into a method on
 `WP_Query`,
 and converts `setup_postdata()` to a wrapper.

 Props boonebgorges, wonderboymusic.
 See #25349.
 Fixes #9256, #20904.
