Move SQL migrations out of line

It makes them much easier to reason about, and allows other SQL tooling
to operate on them like language servers, formatters, etc.

I also brought back the removed migrations such that we can more easily
understand what they were. I included a "-- SKIP" comment describing why
those migrations are now skipped. We no longer skip migrations by
checking if it is empty, but instead check to see if the migration
starts with "-- SKIP".
