Emit nested action events after the transaction completes

Description

Fixes #11172 by storing a queue of nested actionEvents that gets emitted after the main transaction completes. The top level action event will be emitted, followed by the nested action events.

The database in the context is updated from this.knex || getDatabase() to getDatabase() as the emitting of action runs outside of the transaction now.

Sample extension to verify sequence and availability of items

module.exports = function registerHooks({ action }) {
	async function callback(data, { database, schema }) {
		console.dir({ data }, { depth: null });
		console.dir(
			await database
				.select('*')
				.from(data.collection)
				.where(schema.collections[data.collection].primary, '=', data.key ?? data.keys[0]),
			{ depth: null }
		);
	}

	action('items.create', callback);
	action('items.update', callback);
	action('items.delete', callback);
};
