Make trashbin api modules

Apps can register trashbin backends for specific storages,
allowing them to modify trashbin behavior for storages

The old trashbin implementation has been wrapped in a "legacy" backend,
for future work this can be replaced with a new backend that better handles
shares while still keeping the legacy backend around to keep existing trash
from being accessible
