[modular][testing] Test harness component & gtest fixture

This CL introduces two features:
* A component that provides the TestHarness as a service.
  (`modular_test_harness.cmx`)
* A gtest fixture that exposes TestHarness using
  `modular_test_harness.cmx`.

modular_test_harness.cmx is intended to be used by test fixtures in
other languages such as Dart and C++.

Also in this CL:
* TestHarnessImpl will accept and invoke an exit callback if the test
  harness becomes unavailable.

Test: `modular_test_harness_test` exercises the test fixture, which also
exercises modular_test_harness.cmx
