ENH: Add parameter to set cxx test options

Allows remote module projects to pass ctest options such as
excluding invalid tests by name with `-E <test_name>`.

Caveats:
- Several ctest options are already set by the workflow, such as the
  dashboard to receive results, the number of jobs to run, and
  verbosity.
- Only available for cxx workflow.

Closes #5.
