16391a9641 Database: Restore numbered placeholders in wpdb::prepare(). 
[41496] removed support for numbered placeholders in queries send through `wpdb::prepare()`, which, despite being undocumented, were quite commonly used.

This change restores support for numbered placeholders (as well as a subset of placeholder formatting), while also adding extra checks to ensure the correct number of arguments are being passed to `wpdb::prepare()`, given the number of placeholders.

Merges [41662], [42056] to the 4.2 branch.
See #41925.

89333247c9 Database: Hardening to bring wpdb::prepare() inline with documentation. 
`wpdb::prepare()` supports %s, %d, and %F as placeholders in the query string. Any other non-escaped % will be escaped.

0f529b177c WPDB: Remove some of the complexities in ::strip_invalid_text() associated with switching character sets between queries.

b35982cbff Simplify the setup-config.php UI flow and load process. 
When no configuration file is detected, we now redirect to setup-config.php. This process now uses the WordPress bootstrap, rather than a set of fragile hacks.

fixes #28740.

82bdc78500 LIKE escape sanity: 
* Deprecate `like_escape()`
* Add a method to `$wpdb`, `->esc_like()`, and add unit tests

`$wpdb::esc_like()` is not used yet. As such, many unit tests will throw `Unexpected deprecated notice for like_escape`. Subsequent commits will alleviate this.

Props miqrogroove.

fd5e6b5f6b In wpdb, make some things explicitly public. Do not set anything to private. This would instantly blow up hyperdb in the wild.

361e3e1ee6 In wpdb, remove dead code: 
* In `->tables()`, `break` is unreachable after `return`
* In `->query()`, `$return` is always set, so doesn't need an initial value of `0`
* In `->delete()`, `$bits` is unused
