Serial columns without a primary key (cycle/database#106, 2.5.0) were undocumented, and the per-driver behaviour differs a lot: only PostgreSQL has a real non-PK counter, MySQL folds an AUTO_INCREMENT column into the primary key, SQLite and SQL Server have no option for it (#175).

Closes #175.
Primary-key auto-increment was already covered; this documents auto-incremented columns that are not the primary key.
database/declaration.md: a new "Auto-increment Columns Outside the Primary Key" section with per-driver behaviour — PostgreSQLserial()/bigSerial()/smallSerial()(Adding the ability to use serial without primary key database#106, 2.5.0); MySQL, where anautoIncrement: truecolumn is always added to the primary key and the table is created only with the counter first in it; no support on SQLite and SQL Server.annotated/entity.md: an entity example with aserialcolumn and#[GeneratedValue(onInsert: true)], how the value is read back (RETURNINGon PostgreSQL, not on MySQL), and what happens on other drivers.Checked on PostgreSQL 17 and MySQL 8.0 (schema and ORM paths), SQLite, and the column DDL every driver renders, against cycle/database 2.x, cycle/orm 2.x and cycle/annotated 4.x.
