OF-3237: Add exploratory Firebird database support
This is an exploratory change to assess the feasibility of adding Firebird (https://firebirdsql.org) as a supported database back-end for Openfire.
Firebird is an open-source relational database with standard SQL support, backed by the mature Jaybird JDBC driver. The change bundles that driver, adds Firebird to the database-type detection logic, provides an installation schema (adapted from the PostgreSQL schema, with Firebird-compatible types), a schema upgrade script for version 38, a Docker Compose service definition for CI, install and upgrade CI jobs, a preset in the setup wizard, and a section in the database documentation.
