vfio: Introduce new files for CPR definitions and declarations

Browse source 
Gather all CPR related declarations into "vfio-cpr.h" to reduce exposure
of VFIO internals in "hw/vfio/vfio-common.h". These were introduced in
commit d9fa4223b3 ("vfio: register container for cpr").

Order file list in meson.build while at it.
