vfio: Move VFIOAddressSpace helpers into container-base.c

VFIOAddressSpace is a common object used by VFIOContainerBase which is
declared in "hw/vfio/vfio-container-base.h". Move the VFIOAddressSpace
related services into "container-base.c".

While at it, rename :

vfio_get_address_space -> vfio_address_space_get
vfio_put_address_space -> vfio_address_space_put

to better reflect the namespace these routines belong to.

Gather all VFIORegion related declarations and definitions into their
own files to reduce exposure of VFIO internals in "hw/vfio/vfio-common.h".
They were introduced for 'vfio-platform' support in commits
db0da029a185 ("vfio: Generalize region support") and a664477db8da
("hw/vfio/pci: Introduce VFIORegion").

To be noted that the 'vfio-platform' devices have been deprecated and
will be removed in QEMU 10.2. Until then, make the declarations
available externally for 'sysbus-fdt.c'.

vfio: Introduce a new header file for external migration services

The migration core subsystem makes use of the VFIO migration API to
collect statistics on the number of bytes transferred. These services
are declared in "hw/vfio/vfio-common.h" which also contains VFIO
internal declarations. Move the migration declarations into a new
header file "hw/vfio/vfio-migration.h" to reduce the exposure of VFIO
internals.

While at it, use a 'vfio_migration_' prefix for these services.

To be noted, vfio_migration_add_bytes_transferred() is a VFIO
migration internal service which we will be moved in the subsequent
patches.
