The EFI_RETURN_STATUS_EXTENDED_DATA feature from PI-1.7 (<https://mantis.uefi.org/mantis/view.php?id=1885>) enables platform code to learn about boot option failures (loading and launching) via status codes reported by the UEFI Boot Manager. In commit 59541d41633c, we removed all status code support from ArmVirtPkg. Reenable that support now, minimally, just to the extent so we can benefit from the PI-1.7 feature mentioned above: (1) Include the ReportStatusCodeRouterRuntimeDxe driver. This driver produces two protocols, EFI_STATUS_CODE_PROTOCOL and EFI_RSC_HANDLER_PROTOCOL. The former allows DXE phase modules and runtime modules to report (produce) status codes. The latter allows the same types of modules to register callbacks for status code handling (consumption). (Handler registration occurs only at boot time. Status codes are delivered to each handler at runtime as well, unless the handler is unregistered at ExitBootServices().) (2) Resolve ReportStatusCodeLib to a non-Null instance, for DXE_DRIVER modules only. This way DXE_DRIVER modules that use the REPORT_STATUS_CODE_EX() macro and friends will reach EFI_STATUS_CODE_PROTOCOL from point (1). (3) Set PcdReportStatusCodePropertyMask to 3 (the default value is 0). This causes the REPORT_STATUS_CODE_EX() macro and friends to let Progress Codes (bit#0) and Error Codes (bit#1) through to point (1). Debug Codes (bit#2) are filtered out. (4) Include no driver, for now, that registers any status code handler via EFI_RSC_HANDLER_PROTOCOL, from point (1). Status codes that reach ReportStatusCodeRouterRuntimeDxe will be thrown away. (5) Modify only the ArmVirtQemu* platforms. A status code handler will be added to "ArmVirtPkg/Library/PlatformBootManagerLib" in the next patch, and this library instance is not consumed by ArmVirtXen.
