Migrate some of the unit tests at `lib/cmsis_dsp` to the new ztest API: * lib/cmsis_dsp/basicmath * lib/cmsis_dsp/bayes * lib/cmsis_dsp/complexmath * lib/cmsis_dsp/distance * lib/cmsis_dsp/fastmath `lib/cmsis_dsp/common/test_common.h` has been adapted to use the new ztest API for the test variant macros, when enabled.
