Fix cross inclusion between metal/sys.h and /processor/hosted/cpu.h
The fix consists in creating a cpu.c file to avoid inline declaration.
Issue reported by Zephyr twister CI test:
libmetal/lib/include/metal/processor/hosted/cpu.h:19:9:
error: implicit declaration of function ‘metal_wait_usec’
19 | metal_wait_usec(10);
| ^~~~~~~~~~~~~~~
libmetal/lib/include/metal/system/zephyr/sys.h:46:20:
error: conflicting types for ‘metal_wait_usec’; have ‘void(uint32_t)’
46 | static inline void metal_wait_usec(uint32_t usec_to_wait)
| ^~~~~~~~~~~~~~~
libmetal/lib/include/metal/processor/hosted/cpu.h:19:9:
note: previous implicit declaration of ‘metal_wait_usec’ with
type ‘void(uint32_t)’ {aka ‘void(unsigned int)’}
19 | metal_wait_usec(10);
| ^~~~~~~~~~~~~~~
