Upgrade pkg/language_versioning_2_7_test to 2.12/2.13.

This package tests the language versioning infrastructure, in
particular how it interacts with imports, exports, and part
files. With the removal of legacy (pre-2.12) support from Dart, we
need the tests in this package to use newer language versions.
