Refactor the OptimizedBuildTarget base class to more simply handle enabling/disabling build optimizations based on flags. Now all optimizers (aside from the no-op NullOptimizer will have their enabling built into the base class, and also necessitate their get_build_targets and package_outputs functions to be defined in order to not error out. Add the GeneralTestsOptimizer class as well, unimplemented for now. Test: atest build_test_suites_test Bug: 358215235 Change-Id: Ide22c64fc238d754db8d8e76484947401e54e680
