repack: add incremental tree repacking

Browse Source 
Summary:
Previously we only supported full repacks of the manifest stores. This patch
adds incremental repacking for both the shared manifest store and the local
manifest store.

Test Plan:
Did a few pulls to produce a few treemanifest pack files. Ran hg
repack --incremental after each one and verified it was a no-op until there were
enough pack files to trigger the repack.

Will add tests later today.
