Revert "cpu: Move cpu_common_props to hw/core/cpu.c"

This reverts commit 1b36e4f.

Despite a comment saying why cpu_common_props cannot be placed in
a file that is compiled once, it was moved anyway.  Revert that.

Since then, Property is not defined in hw/core/cpu.h, so it is now
easier to declare a function to install the properties rather than
the Property array itself.
