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.

The `CMSIS_NN` Kconfig previously depended on the `CMSIS_DSP` Kconfig,
and this placed the "CMSIS-NN Library Support" prompt under the "CMSIS-
DSP Library Support" menu (note that CMSIS-DSP is a menuconfig).
Since the CMSIS-NN library, although it requires the CMSIS-DSP library,
is not a subordinate component of the CMSIS-DSP library, remove its
dependency on `CMSIS_DSP` and make it select the Kconfig symbol
instead.

Change the CPU_CORTEX_R kconfig option to CPU_AARCH32_CORTEX_R to
distinguish the armv7 version from the armv8 version of Cortex-R.

Add the inclusion of the Common Peripheral Access Layer for aarch32
Cortex-A SoCs in combination with the respective SoC's header file,
in which the feature flags evaluated in core_ca.h must be provided.
The corresponding CMSIS include path is added to the build by setting
the HAS_CMSIS_CORE_A Kconfig item for all aarch32 Cortex-A CPUs.

This commit updates the west.yml to point to the commit that adds the
CMSIS-Core(A) and defines the configurations to enable it, in
preparation for the AArch32 Cortex-A architecture support in Zephyr.
