+/**
+ Register the callback function for ReportStatusCode() notification.
+
+ When this function is called the function pointer is added to an internal list and any future calls to
+ ReportStatusCode() will be forwarded to the Callback function. During the bootservices,
+ this is the callback for which this service can be invoked. The report status code router
+ will create an event such that the callback function is only invoked at the TPL for which it was
+ registered. The entity that registers for the callback should also register for an event upon
+ generation of exit boot services and invoke the unregister service.
+ If the handler does not have a TPL dependency, it should register for a callback at TPL high. The
+ router infrastructure will support making callbacks at runtime, but the caller for runtime invocation
+ must meet the following criteria:
+ 1. must be a runtime driver type so that its memory is not reclaimed
+ 2. not unregister at exit boot services so that the router will still have its callback address
+ 3. the caller must be self-contained (eg. Not call out into any boot-service interfaces) and be
+ runtime safe, in general.
+
+ @param[in] Callback A pointer to a function of type EFI_RSC_HANDLER_CALLBACK that is called when
+ a call to ReportStatusCode() occurs.
+ @param[in] Tpl TPL at which callback can be safely invoked.

+ @retval EFI_INVALID_PARAMETER The callback function was NULL.
+ @retval EFI_OUT_OF_RESOURCES The internal buffer ran out of space. No more functions can be
