Migrator: Add a progress bar for explainMigration, which can take a long time.

This shows progress for work which happens after the migration suggestions have
been generated. This work is generating instrumentation details for the front
end.

When migrating the analyzer package, the progress indicated by this third
progress bar takes approximately the same time as generating suggestions (on
the same order of magnitude).
