WordPress' code just... wasn't.
This is now dealt with.
Props jrf, pento, netweb, GaryJ, jdgrimes, westonruter, Greg Sherwood from PHPCS, and everyone who's ever contributed to WPCS and PHPCS.
Fixes#41057.

On newer versions of MySQL, an error was being thrown when creating a table with an index that we wanted to be silently truncated.
To avoid this, the test now tries to use a newer InnoDB file format where available, and skips the test when that happens.

In [31349], core `varchar` column key lengths were changed from 255 to 191 to support the 767 byte index size limit on standard utf8mb4 MySQL installs. This changes the DB schema tests to match.

If index lengths change in table definitions, we don't recreate the index - instead, we throw a database error, as `dbDelta()` tries to create a new index with the same name.
It's better to leave the index as is, MySQL doesn't have an efficient process for resizing indices, and dropping/creating is a slow process which we don't want to trigger automatically.

When comparing index definitions, normalise the index names to lower case, as they are not case sensitive within MySQL.
Fixes#34874.

`dbDelta()` compares the index definitions against the result of `SHOW INDEX FROM $table_name`. This requires a specific format so indices are not unnecessarily re-created. This format wasn't ensured, until now.
* Parse the raw index definition to extract the type, name and columns so a normalized definition can be built (#20263, #34873).
* Standardize on uppercase types (#34871) and on 'KEY'. 'INDEX' is only a synonym for 'KEY'.
* Escape index names with backticks (#20263).
* Normalize columns: Ignore ASC and DESC definitions (#34959), remove whitespaces (#34869) and escape column names with backticks (#20263).
* Add backticks to all index change queries (#20263).

`dbDelta()` already supported spatial fields (by virtue of not checking field types), so it's nice to round that out with spatial key support, too.

When upgrading to `utf8mb4`, `TEXT` fields will be upgraded to `MEDIUMTEXT` (and likewise for all other `*TEXT` and `*BLOB` fields). This is to allow for the additional space requirements of `utf8mb4`.
On the subsequent upgrade, after the `utf8mb4` upgrade, `dbDelta()` would try and downgrade the fields to their original size again. At best, this it a waste of time, at worst, this could truncate any data larger than the original size. There's no harm in leaving them at their original size, so let's do that.
Fixes#36748.

Test to make sure that dbDelta properly inserts a value into the DB.

Add new tests for more parts of dbDelta. This was cleaned up and prepared for commit at #wcphilly contributor day.
