fix(core): missing-injectable migration should handle forwardRef (#33286)

Currently the migration is unable to migrate instances where
the provider definition uses `forwardRef`. Since this is a
common pattern, we should support that from within the migration.

The solution to the problem is adding a foreign function resolver
to the `PartialEvaluator`. This basically matches the usage of
the static evaluation that is used by the ngtsc annotations.
