Enable Android Lint tests for AndroidFrameworkLintChecker

Create AndroidFrameworkLintCheckerTest module and add
.allowMissingSdk(true) to all tests to enable tests running on gerrit.

"unit_test: true" marks the module as a unit test target which runs it
on the host without a device and it automatically gets onboarded in the
presubmit.

Bug: 157626959
Test: atest AndroidFrameworkLintCheckerTest --host
