ext: hal: cmsis: Update references to HAS_CMSIS to HAS_CMSIS_CORE.

This commit updates all references to HAS_CMSIS to use HAS_CMSIS_CORE
instead. With the changes introduced to allow multiple CMSIS variants
to be specified, the latter is semantically equivalent to the former.

For more details, see issue #19717.
