target: Introduce and use OBJECT_DECLARE_CPU_TYPE() macro

Replace the boilerplate code to declare CPU QOM types and macros, and forward-declare the CPU instance type. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20220214183144.27402-14-f4bug@amsat.org>
