acpi: Add acpigen_write_OSC_pci_domain
Add dynamic PCI domain _OSC ASL generation codes, supporting both
PCIe and CXL domains.
Dynamic SSDT generation is used to generate a list of ASL device
objects based on FSP outputs (e.g. the SoC/SKU configurations)
and _OSC is a method inside these objects (hence it would be
straightforward to be generated altogether, plus some C codes
managed boot configs could be referenced as well).
This usage is optional. It is helpful for cases where the same
code set supports multiple SKUs/SoCs (difficult to be handled by
one set of static SSDT), and the CPU performance is good enough
to run SSDT generation logics with minimal costs.
