3942226c90 WPDB: Allow null values in the CRUD functions.
Specifically, `::insert()`, `::replace()`, `::update()`, and `::delete()` can now set a column to `NULL`, or add the `IS NULL` condition to the `WHERE` clause.

This is based on [backpress 279].

Props pento, nbachiyski, sorich87.

Fixes #15158.

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.

Fixes #33501.

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.

60b0cd7943 The keyword elseif should be used instead of else if so that all control keywords look like single words.
This was a mess, is now standardized across the codebase, except for a few 3rd-party libs. 

See #30799.

23707b1ada Convert various uses of (optional) in core parameter descriptions to use the style prescribed in the inline documentation standards for PHP.
The style for marking parameters optional in inline PHP docs is: `@param type $var Optional. Description. Accepts. Default.`, where Accepts can be omitted on a case-by-case basis.

Props coffee2code.
