When I first implemented this I thought that checking exports wasn't
needed, since it's not allowed for a migrated library to re-export
symbols defined in an unmigtated library. But it turns out we still
do need to include exports in the check, since there might be migrated
libraries that are only reachable in the transitive dependency graph
via an export, and we need to check that *those* libraries don't
import unmigrated code.

`Null` we use a special messages that doesn't state that
"'Null' is nullable". Cases where `Null` is part of the type or where
the expression of type `Null` is derived from a collection are not

Instead of running `pub outdated` to see if the user's dependencies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`pub outdated`, because it is able to ignore files in transitive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.

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).

Early in the development of the migration tool, due to language
versioning support being incomplete, it didn't have a good way to
distinguish opted in from opted out code, so we had the convention
that any code not being migrated was opted in. Now that we have
language versioning support, we need to explicitly opt that code in.
Without this change, we'll get bogus failures when we add logic to
detect unmigrated dependencies.

Fields initialized in `setUp` are late.
Variables initialized with implicit casts like:
ClassDeclaration clazz = unit.declarations[0];
would need a cast:
ClassDeclaration clazz = unit.declarations[0] as ClassDeclaration;
so they are updated to use var, which is more idiomatic:
var clazz = unit.declarations[0] as ClassDeclaration;

As discussed in
https://github.com/dart-lang/sdk/issues/44031#issuecomment-720967259,
we want to encourage users to publish null safe packages with an SDK
min constraint matching the SDK version that was used for the
migration, e.g. `2.12.0-18.0.beta`. However, we also want to make
sure that users doing migration via internal, dev, or bleeding edge
builds publish their null safe packages don't wind up inadvertently
publishing packages that are un-resolvable with the latest beta SDK,
so if the user is on one of those versions, we'll set their SDK min
constraint to `2.12.0-0`.
And of course, once the feature ships to stable, we'll want users to
publish their null safe packages with an SDK min constraint matching
the version in which null safety shipped to stable.
This CL implements all of that functionality, and tests it by
overriding the `version` file in the analyzer's mock SDK.
