math: Introduce a DSP basicmath subsystem with a cmsis backend Introduce an API mirroring the CMSIS-DSP's basicmath. If CMSIS_DSP is enabled, then it will by default be used as a backend. Developers may opt into a custom backend by setting CONFIG_DSP_BACKEND_CMSIS=n. If done, the application must provide `zdsp_backend/dsp.h` and optionally implement the functions in its own .c files.

Include the DSP (Digital Signal Processing) subsystem as a part of the
Zephyr build. This enables applications to include and call into the
<zephyr/dsp/dsp.h> header.

Implement the various zephyr DSP functions using the CMSIS-DSP library. This feature
requires the CMSIS module to be selected.

bool "Do not use any Zephyr backends for DSP"
help
Rely on the application to provide a custom DSP backend. The implementation should be
added to the 'zdsp' build target by the application or one of its modules.
