softmmu: List CPU types again

Commit e0220bb5b2 made cpus.c target-agnostic but didn't notice
the cpu_list() function is only defined in target-specific code
in "cpu.h". Move list_cpus() declaration to "exec/cpu-common.h"
because this function is not softmmu-specific and can also be
used by user-mode, along with moving its implementation to cpu.c,
which is compiled per target.

Fixes: e0220bb5b2 ("softmmu: Build target-agnostic objects once")
