MDL-59700 filestorage: Rework repositories to avoid add_file_to_pool

Browse Source 
For historical reasons repositories need to call add_file_to_pool
to sync file records. However now that a before_file_created hook
has been added additional information is needed by add_file_to_pool.

Ideally add_file_to_pool and friends will become private/protected,
so we need to remove all uses of it in core.

This patch adds some new methods to the file class to allow syncing
to be managed internally by the file and the file_storage class.
