PciOutOfResourceSetupPage

UEFI DXE driver for the "PCI Out of Resource" setup page. Installs HII Config Access protocol to allow the BIOS setup UI to display a form when PCI devices exhaust bus/resource allocation. Includes 35 functions covering IFR bytecode construction, HII configuration routing, string utilities, CMOS debug level access, and HOB parsing. This is a self-contained HII form driver with no external protocol dependencies beyond the standard UEFI HII and DebugMask protocols.
