DynamicTablesPkg: AmlLib: AmlAddPrtEntry() to handle GSI
In ACPI 6.4, s6.2.13, _PRT objects describing PCI legacy interrupts
can be defined following 2 models.
In the first model, _PRT entries reference link devices. Link devices
then describe interrupts. This allows to dynamically modify
interrupts through _SRS and _PRS objects and to choose exactly the
interrupt type (level/edge triggered, active high/low).
In the second model, interrupt numbers are described in the _PRT entry.
The interrupt type is then assumed by the OS.
AmlAddPrtEntry() currently only handles the first model. Make
changes to also handle the second model.
