feat: add database type validation and conditional DB vars to common.sh

Browse Source 
Add validate_db_type() accepting sqlite3/mysql/postgres/mssql. Update
GITEA_DB_TYPE validator from nonempty to db_type. Add conditional DB
validation arrays (host, port, name, user, passwd) required when DB
type is not sqlite3. Rename SSL conditional arrays for clarity.
