FmpDevicePkg/FmpDxe: Use new FmpDeviceLib APIs
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1525
Update FmpDxe to support multiple controllers and use
new FmpDeviceLib APIs to support Stop/Unload and to
set the context for the worker functions in the
FmpDeviceLib.

+ - Validate the image is a supported image for this device. The function returns EFI_ABORTED if

+ validation failed. The function returns EFI_ABORTED if the data is invalid.

+ firmware image version is older than the current firmware image version or bad image checksum.
+ Sensitive operations such as those wiping the entire firmware image and render the device to be
