Now that `MigrationCliRunner.shouldBeMigrated` has the correct
signature and internal clients no longer use
`MigrationCliRunner.shouldBeMigrated2`, we can remove
`MigrationCliRunner.shouldBeMigrated2`.

This is non-breaking since `shouldBeMigrated` is unreferenced outside
the nnbd_migration package). Once this lands, we can switch clients
from overriding/calling `shouldBeMigrated2` back to `shouldBeMigrated`
and then eliminate `shouldBeMigrated2`.

This change changes `MigrationCliRunner.shouldBeMigrated` to forward
to a transitional method `MigrationCliRunner.shouldBeMigrated2`, which
lacks the now-unused `context` argument. After this lands, internal
clients will be switched to overriding/calling `shouldBeMigrated2`
instead of `shouldBeMigrated`.
Once no clients remain that refer to `shouldBeMigrated`, the `context`
argument will be removed from it (this will be non-breaking since
`shouldBeMigrated` will at that point be unreferenced outside the
nnbd_migration package). After that, we will switch clients back to
overriding/calling `shouldBeMigrated` and eliminate
`shouldBeMigrated2`.

* Rename isPreviewServerRunnning to isPreviewServerRunning
* Fix top "Migrating" checkbox upon navigation.
This change does not completely solve google3-compatibility, just the
web preview UI portion.

Since the EdgeBuilder overrides VisitNode, it wasn't getting the
benefit of the error recovery behavior provided by the
PermissiveModeVisitor mixin. This CL replicates some of the
functionality of PermissiveModeVisitor in the EdgeBuilder._dispatch
method so that it applies throughout the EdgeBuilder's visiting
process.
This uncovered a second bug: when an exception is reported, and the
user hasn't passed in the `--ignore-exceptions` flag, the migration
tool tries to exit immediately by throwing an error of type
MigrationExit, but this was being caught by the error recovery logic,
so the tool wouldn't actually stop reliably. This CL changes the
exception reporting code so that it re-throws MigrationExit when
necessary to ensure quick termination.

I will need to add another callback in a follow-up CL, and it seems
silly to pass a bunch of closures to the DartFixListener constructor.

Previously, the user experience was an `UnimplementedError` with no
further information. Now the user gets an error message telling them
how they need to update the pubspec, which I believe was the original
implementation intent.
Note that the field `_packageIsNNBD` has been removed. Although the
comment for this field said it was tracking whether the package was
opted in to null safety, it actually had no effect (since the only
code path that would set it to `false` was after the
`UnimplementedError` and thus unreachable).

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).

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.

The output the migration tool generates when the web preview is
disabled shows a complete diff of all changes the tool will make, so
it's really a misnomer to call it a "summary".

This CL unblocks the internal SDK roll by restoring the migration
tool's `MigrationCli.addCoreOptions` method (which is currently used
internally). It also adds a replacement, `MigrationCli.options`,
which is more robust because it allows the client to choose which
options to include and which options to exclude.
Once this CL has rolled in, I'll update the internal code base to use
the new `MigrationCli.options` method and then remove the deprecated
`addCoreOptions` method.
