CTest support for integration tests (#5101)
Add CTest support for integration tests. This is our interim solution
for integration testing support while we find a long-term solution. It
results from tests that were previously Bazel-only (because TF) and now
are CMake-only (because maintaining support for Python in Bazel was
determined to be not worth the effort).
The approach is to open-source our internal BUILD files for Blaze
(Google's internal version of Bazel, which happens to do some rather
different things with Python). These rely on a Starlark rule for
expanding a test matrix that is pretty painful to implement in CMake.
The author apologizes.
This enables 1317 new test targets.
Incidentally, it makes the tests run in parallel, which should speed
things up quite a bit...
