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.

Add functionality in build_test_suites.py to not build targets if
their outputs are not used in the test configurations saved in the build
context. If none of the tests reference the targets' outputs they will
not be built at all.
Note that the corresponding flags will need to be enabled for these
optimizations to take place.

Ensure that output and errors from the underlying build command are
streamed for real-time build progress updates and debugging.
This change strips out all code that is currently unecessary and adds
tests for the remaining functionality.
