Migration: replace `pub outdated` check with a check on transitive imports.

Instead of running `pub outdated` to see if the user's dependencies
have been migrated yet, the migration tool now examines all of the
transitive import dependencies of the user's code to see if they are
opted in to null safety.  This produces a more accurate result than
`pub outdated`, because it is able to ignore files in transitive
package dependencies that aren't reachable via imports
(e.g. references to `package:analyzer` brought in by `package:test`).

Fixes #44061.
