Summary

[rickogden]

I've started work on the Symfony AI store integration. It turns out it needs a vector index, which MariaDB supports by MySQL9 doesn't. I've now added the VECTOR index support to MariaDB in this PR.

Been doing some more investigation today. It looks like the problem that was being hit with mysql is also in existence with pdo on PHP 8.3. For some reason the database doesn't accept the binary value. Annoyingly, the only way I've been able to get it to work on PHP < 8.4 is by using VEC_FromText().
