84b702009b 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 4.5 branch.
See #41925.

ffc4d6965c WPDB: Fall back to the connection charset when sanity checking strings. 
If `DB_CHARSET` isn't defined (or is empty), `wpdb::$charset` will be empty, too. `wpdb::strip_invalid_text()` assumes that it isn't empty, however, so we need to fall back to the connection character set when we're running our sanity checks.

9347f1af71 WPDB: Make sure we don't run sanity checks on DB dropins. 
Previously, we'd run the sanity checks if `is_mysql` was not set to `false`. This caused problems for DB drop-ins that didn't define `is_mysql` at all. Instead, we can just check if `is_mysql` is `empty()`.

Also fix some unit tests that accidently ran correctly because of the strict `false ===` comparison.

8b4a5d1ec0 Introduce metadata for taxonomy terms. 
Adds a new table to the database schema (`wp_termmeta`), and a set of
`*_term_meta()` API functions. `get_terms()` and `wp_get_object_terms()`
now also support 'meta_query' parameters, with syntax identical to other
uses of `WP_Meta_Query`.

When fetching terms via `get_terms()` or `wp_get_object_terms()`, metadata for
matched terms is preloaded into the cache by default. Disable this behavior
by setting the new `$update_term_meta_cache` paramater to `false`.

To maximize performance, within `WP_Query` loops, the termmeta cache is *not*
primed by default. Instead, we use a lazy-loading technique: metadata for all
terms belonging to posts in the loop is loaded into the cache the first time
that `get_term_meta()` is called within the loop.

cbacb92dae Enable utf8mb4 for MySQL extension users. Previously utf8mb4 was limited to MySQLi users only unintentionally. 
This change does the following things
 * Allows utf8mb4 for the MySQL extension
 * Re-runs the utf8->utf8mb4 conversion for single sites, this will do nothing for tables already converted
 * Re-runs the utf8->utf8mb4 conversion for global tables in multisite when the environment supports utf8mb4
 * Removes upgrade_420() calling as upgrade_430() will perform those changes now instead

The index shortenings should have still taken place on utf8 sites previously, so there's no need to run those again.
