Some declarations are only used within hw/core/, in particular
by the 3 cpu-{common,user,system}.c. Restrict the declarations
scope by moving them to a new "cpu-internal.h" local header.

Rename cpu_exec_initfn() -> cpu_exec_init() because we usually
have the 'fn' suffix for handler, not API entry point methods.
