vfio: add vfio-pci-base class
Split out parts of TYPE_VFIO_PCI into a base TYPE_VFIO_PCI_BASE, although we have not yet introduced another subclass, so all the properties have remained in TYPE_VFIO_PCI.
Note that currently there is no need for additional data for TYPE_VFIO_PCI, so it shares the same C struct type as TYPE_VFIO_PCI_BASE, VFIOPCIDevice.

vfio: Introduce new files for VFIORegion definitions and declarations
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/igd: Decouple common quirks from legacy mode
So far, IGD-specific quirks all require enabling legacy mode, which is toggled by assigning IGD to 00:02.0. However, some quirks, like the BDSM and GGC register quirks, should be applied to all supported IGD devices. A new config option, x-igd-legacy-mode=[on|off|auto], is introduced to control the legacy mode only quirks. The default value is "auto", which keeps current behavior that enables legacy mode implicitly and continues on error when all following conditions are met. * Machine type is i440fx * IGD device is at guest BDF 00:02.0
If any one of the conditions above is not met, the default behavior is equivalent to "off", QEMU will fail immediately if any error occurs.
Users can also use "on" to force enabling legacy mode. It checks if all the conditions above are met and set up legacy mode. QEMU will also fail immediately on error in this case.
Additionally, the hotplug check in legacy mode is removed as hotplugging IGD device is never supported, and it will be checked when enabling the OpRegion quirk.

For now, to align with current legacy mode behavior, it returns and proceeds on error. Later it will fail on error after decoupling the quirks from legacy mode.

IGD devices require device-specific quirk to be applied to their PCI config space. Currently, it is put in the BAR4 quirk that does nothing to BAR4 itself. Add a placeholder for PCI config space quirks to hold that quirk later.

vfio/igd: Consolidate OpRegion initialization into a single function
Both x-igd-opregion option and legacy mode require identical steps to set up OpRegion for IGD devices. Consolidate these steps into a single vfio_pci_igd_setup_opregion function.
The function call in pci.c is wrapped with ifdef temporarily to prevent build error for non-x86 archs, it will be removed after we decouple it from legacy mode.
Additionally, move vfio_pci_igd_opregion_init to igd.c to prevent it from being compiled in non-x86 builds.

vfio/igd: add new bar0 quirk to emulate BDSM mirror
The BDSM register is mirrored into MMIO space at least for gen 11 and later devices. Unfortunately, the Windows driver reads the register value from MMIO space instead of PCI config space for those devices [1]. Therefore, we either have to keep a 1:1 mapping for the host and guest address or we have to emulate the MMIO register too. Using the igd in legacy mode is already hard due to it's many constraints. Keeping a 1:1 mapping may not work in all cases and makes it even harder to use. An MMIO emulation has to trap the whole MMIO page. This makes accesses to this page slower compared to using second level address translation. Nevertheless, it doesn't have any constraints and I haven't noticed any performance degradation yet making it a better solution.
