bionic: Add tests for cpu target features
This adds actual tests to verify we are enabling basic
These tests are intended to be expanded as we require
stricter target features.
These tests depend on the existence of the cpu-target-features
executable on the test DUTs.
Bug: 354747380
Test: Presubmits pass
