ext: hal: cmsis: Add HAS_CMSIS_CORE configuration.

Browse source 
The existing implementation used HAS_CMSIS configuration to specify
that CMSIS-Core(M) is used; when, in fact, there are other CMSIS
variants available such as CMSIS-Core(A) and CMSIS-DSP available.

This commit replaces the existing HAS_CMSIS configuration with
HAS_CMSIS_CORE to clarify that CMSIS-Core is used. It also introduces
the CMSIS-Core variant configuration, HAS_CMSIS_CORE_M, that is
automatically selected when HAS_CMSIS_CORE is enabled.

For more details, see issue #19717.

The ARM Cortex Microcontroller Software Interface Standard (CMSIS) defines a
set of standard interfaces to ARM Cortex-M SOCs. In particular, the CMSIS-CORE
component standardizes the software interface to core and peripheral registers,
as well as exception names and the system clock frequency. Multiple SOC
vendors, including NXP and Nordic Semiconductor, include the CMSIS-CORE header
files in their SOC header files. These SOC header files are in turn used by
the vendor's peripheral drivers.
