[GITEA] admin: "Self Check" should only show for some db types
The "Self Check" menu essentially runs the collation check that is also
performed at startup, and displays the results. This is only a thing for
MariaDB/MySQL and MSSQL. As such, the menu item should only be available
for these database types.

[GITEA] tests: A workaround for the MySQL collation tests
Because Forgejo run mysqld with `--innodb-flush-method=nosync` to speed
up the test suite, there are situations where a larger, database-wide
operation does not always fully manifest until later, not even when it
is wrapped in a transaction, nor when we use `FLUSH TABLES` and similar
methods.

In the case of the MySQL collation test, this *sometimes* results in the
database still responding with the old collation to a reader, even after
an `ALTER DATABASE ... COLLATE ...`.

In order to be able to still use the aforementioned flag and enjoy its
benefits, add a five second sleep between `db.ConvertDatabaseTable()`
and `db.CheckCollations()` in the `TestDatabaseCollation()` set of
tests.

This is not a fix - I don't think there is one possible -, but a
workaround. If it breaks again, the correct fix will be to remove the
flag from `mysqld` (it's not a supported flag to begin with).

Recommend/convert to use case-sensitive collation for MySQL/MSSQL (#28662)
Mainly for MySQL/MSSQL.

It is important for Gitea to use case-sensitive database charset
collation. If the database is using a case-insensitive collation, Gitea
will show startup error/warning messages, and show the errors/warnings
on the admin panel's Self-Check page.

Make `gitea doctor convert` work for MySQL to convert the collations of
database & tables & columns.

* Fix #28131

## ⚠️ BREAKING ⚠️

It is not quite breaking, but it's highly recommended to convert the
database&table&column to a consistent and case-sensitive collation.
