Have ART run-tests part of CTS (and MCTS) compile against the test API.

This change amends the `regen-test-files` generator to add an explicit
`sdk_version` property to the build recipe of the following tests:

* `art-run-test-018-stack-overflow`
* `art-run-test-048-reflect-v8`

The corresponding changes in the generated test files were added
previously (manually) in
https://android-review.git.corp.google.com/c/platform/art/+/3119091.

Flag: TEST_ONLY
Test: Run `test/utils/regen-test-files` and verify it is a no-op
