[PATCH v6 18/18] cpu: Restrict "hw/core/sysemu-cpu-ops.h" to target/cpu.c

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Somehow similar to commit 78271684719 ("cpu: tcg_ops: move to
tcg-cpu-ops.h, keep a pointer in CPUClass"):

We cannot in principle make the SysEmu Operations field definitions
conditional on CONFIG_SOFTMMU in code that is included by both
common_ss and specific_ss modules.

Therefore, what we can do safely to restrict the SysEmu fields to
system emulation builds, is to move all sysemu operations into a
separate header file, which is only included by system-specific code.

This leaves just a NULL pointer in the cpu.h for the user-mode builds.
