Instead of forcing use of NEWLIB_LIBC, select any available complete C
library implementation. Add CONFIG_REQUIRES_FLOAT_PRINTF where needed.

Use CMSIS-DSP from its new realm. This also changes change how you
initialize FFT tables as well to use arm_cfft_init_64_f32 if you
know the FFT size in advance rather than the generic initialization
arm_cfft_init_f32.

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.

This commit adds the test application for the CMSIS-DSP 'complex math'
functions.
This test application is loosely based on the C++ test suite included
in the upstream CMSIS-DSP distribution.
