Summary: This `break` statement causes `./bin/hunks migrate` to only migrate one-hunk-at-a-time, which is unnecessary and slightly misleading. Instead, allow the script to migrate //all// legacy hunks to modern storage. In particular, this means that we can recommend that installs run this command sometime before D13222 is landed.
Test Plan: It's a pain to setup the data necessary to test this, but this is identical to the change that I made on our production install when I migrated our hunk storage.

Summary: Ref T4045. Ref T5179. When saving a modern hunk, deflate it if we have the function and deflating it will save a nontrivial number of bytes.
Test Plan:
- Used `bin/hunks migrate` to move some hunks over, saw ~70-80% compression on most standard hunks.
- Viewed changesets using compressed hunks.
- Profiled `gzinflate()` and verified the cost is trivial (<< 1ms) at least for normal diffs.

Summary:
Ref T4045. Ref T5179. While we'll eventually need to force a migration, we can let installs (particularly large installs) do an online migration for now. This moves hunks to the new storage format one at a time.
(Note that nothing writes to the new store yet, so this is the only way to populate it.)
WARNING: Installs, don't run this yet! It won't compress the data. Wait until it can also do compression.
Test Plan: Added a `break;` after migrating one row and moved a few rows over. Spot checked them in the database and viewed the affected diffs.
