* Reuse allocator (dgraph-io#7360)

Instead of creating a new z.Allocator for every encoder, this PR reuses the allocator. On a 21M dataset, bulk loader takes 2m22s on master, and only 1m35s on this PR. That's a major 35% performance improvement.

fix(sort): Fix multi-sort with nils (dgraph-io#7432) (dgraph-io#7444)

Fix the behavior of multi-sort. All the nil values are appended at the end of
the result irrespective of ascending or descending sort. This change also
fixes a bug due to not appending the nil values in the values list,
corresponding to the UIDs appended in the UID list with nil predicates.
