Deletes file.
If file is a directory, its contents are deleted recursively before file itself is deleted. The recursive
delete operation will stop on the first error.
If cancellable is not null, then the operation can be cancelled by triggering the cancellable object from
another thread. If the operation was cancelled, the error CANCELLED will be returned.
