Open source the configuration tests.

- update the MOCK_CROSSTOOL to provide more stuff needed by tests
- add a THIS_IS_BAZEL constant to allow disabling individual test cases
- disable some tests in Bazel

The disabled tests are mainly due to differences in the test setup - making
the test setups more similar will largely fix that. I think we'll make some
changes to our internal setup, too, not just the external one. For example,
the use of 'k8' and 'piii' to refer to 'x86_64' and 'x86' seems archaic.

I decided to leave the dependency on the C++ and Java configurations rather
than rewriting the tests to use mock configurations. That would be nicer, but
also requires significantly more work.
