Add option test_min_api_level and test_min_sdk_version for auto-generated test config

The new option will allow the auto-generated test config for cc_test to
include MinApiLevelModuleController and check the api-level before test.

Bug: 140912549
Test: 1. $vi platform_testing/tests/example/native/Android.bp
      2. add
          test_min_api_level: 29,
          or
          test_min_sdk_version: 29,
      3. $m -j hello_world_test
      4. check hello_world_test.config
