Report status code to all supported device.
This function implements EFI_STATUS_CODE_PROTOCOL.ReportStatusCode().

@param CodeType Indicates the type of status code being reported.
@param Value Describes the current status of a hardware or software entity.
This included information about the class and subclass that is used to
classify the entity as well as an operation.
@param Instance The enumeration of a hardware or software entity within
the system. Valid instance numbers start with 1.
@param CallerId This optional parameter may be used to identify the caller.
This parameter allows the status code driver to apply different rules to
different callers.
@param Data This optional parameter may be used to pass additional data.
@retval EFI_SUCCESS The function completed successfully
@retval EFI_DEVICE_ERROR The function should not be completed due to a device error.
