system: Move cpu_physical_memory_*() declarations to 'system/physmem.h'

Browse Source 
The following cpu_physical_memory_*() methods do not involve any
vCPU but only access physical memory:

 - cpu_physical_memory_read()
 - cpu_physical_memory_write()
 - cpu_physical_memory_map()
 - cpu_physical_memory_unmap()

Rename them removing the 'cpu_' prefix, and move then to the
"system/physmem.h" header with the other methods involved in
global physical address space.

Mechanical change using sed, then adding missing headers manually.

No logical change intended.
