[CMakeProjectManager] full ctest support

(following issue QTCREATORBUG-23312)

Hi,

A typical cmake project contains all sort of tests, incl. non pure c++ tests such as python scripts, unittest, etc.

It is totally fine to add them as ctest (add_test in cmake) but unfortunately they does not appear in QtCreator.
Right now, you don't even know they exist from inside QtCreator.

QtCreator is only displaying googletest/qttest/quicktest/boosttest.

Would it be possible to see/filter/run any ctest?

Even if their results cannot be parsed in the "Test Results" console. Maybe it would be possible to also do so based on cmake macros such as CTEST_CUSTOM_ERROR_MATCH / CTEST_CUSTOM_WARNING_MATCH

Thanks!
