[feature] Run ANALYZE after migrations on SQLite (#2428)

* [feature] Run ANALYZE after migrations on SQLite

This ensures that at the end of migrations, we run ANALYZE if we're
using SQLite. This should be relatively quick and guarantees that the
table and index statistics have been updated. This helps to ensure the
query planner makes better choices when it comes to picking which
indexes are used when running queries.

* [chore] use ExecContext

Uses ExecContext so we pass the context through, this is helpful for
anyone running with tracing enabled
