PerformancePkg Dp_App: Use Image->FilePath to get name for SMM drivers
This enhancement is to use the FilePath field in the loaded image protocol to find the name of an image as a fallback for when the loaded image device path protocol is not installed on the image handle. This is necessary because the SMM core does not install the loaded image device path protocol, so DP was displaying "Unknown Driver Name" for every SMM driver.
