Add add-database and remove-database lifecycle events

Browse source 
Fire plugin-visible events from Datasette.add_database() and
.remove_database() so plugins can react to databases being attached or
detached at runtime. Dispatch is best-effort fire-and-forget: events only
fire when startup has completed and an event loop is running, and
remove-database fires after close() so queued writes are flushed before
listeners run.

Motivating consumer is datasette-litestream, which needs to register newly
attached databases with its replication daemon.
