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.

Even though it has an 'amd_' prefix, the amd_pci_domain_fill_ssdt
implementation doesn't contain any AMD-specific code and can also be
used by other SoCs. So factor it out, move the implementation to
src/acpi/acpigen_pci_root_resource_producer.c, and rename it to
pci_domain_fill_ssdt. When a SoC now assigns pci_domain_fill_ssdt to its
domain operation's acpi_fill_ssdt function pointer, the PCI domain
resource producer information will be added to the SSDT.
