SignedCapsulePkg/SystemFirmwareUpdate: Add SystemFirmwareUpdate. 

SystemFirmwareUpdate supports update system firmware via UEFI FMP capsule.

SystemFirmwareReportDxe.inf can be included in system BIOS. It is a
lightweight FMP protocol implementation and it only reports FMP
information, so that ESRT table can report the system firmware
information. SetImage() will dispatch the driver FV in the EDKII system
FMP image (SystemFirmwareUpdateDxe),
then pass thru the SetImage() request to latter.

SystemFirmwareUpdateDxe.inf can be included in EDKII system capsule image.
It is a full feature FMP protocol implementation and supports SetImage().
It can be used to update the system firmware.
SystemFirmwareUpdateDxe.inf can also be included in system firmware.
If so SystemFirmwareReportDxe.inf is not needed.

SystemFirmwareUpdateDxe SetImage() will perform the FMP authentication and
version check. If and only if the FMP authentication passes, and new
EDKII system capsule version is no less than current system firmware
LowestSupportedVersion, the system firmware will be updated.

Updates the firmware image of the device.
This function updates the hardware with the new firmware image.
This function returns EFI_UNSUPPORTED if the firmware image is not updatable.
If the firmware image is updatable, the function should perform the following minimal validations
before proceeding to do the firmware image update.
- Validate the image authentication if image has attribute
IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED. The function returns
EFI_SECURITY_VIOLATION if the validation fails.
- Validate the image is a supported image for this device. The function returns EFI_ABORTED if
the image is unsupported. The function can optionally provide more detailed information on
why the image is not a supported image.
- Validate the data from VendorCode if not null. Image validation must be performed before
VendorCode data validation. VendorCode data is ignored or considered invalid if image
validation failed. The function returns EFI_ABORTED if the data is invalid.
VendorCode enables vendor to implement vendor-specific firmware image update policy. Null if
the caller did not specify the policy or use the default policy. As an example, vendor can implement
a policy to allow an option to force a firmware image update when the abort reason is due to the new
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
non-functional should be encoded in the image itself rather than passed with the VendorCode.
AbortReason enables vendor to have the option to provide a more detailed description of the abort
reason to the caller.

/**
Updates the firmware image of the device.
This function updates the hardware with the new firmware image.
This function returns EFI_UNSUPPORTED if the firmware image is not updatable.
If the firmware image is updatable, the function should perform the following minimal validations
before proceeding to do the firmware image update.
- Validate the image authentication if image has attribute
IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED. The function returns
EFI_SECURITY_VIOLATION if the validation fails.
- Validate the image is a supported image for this device. The function returns EFI_ABORTED if
the image is unsupported. The function can optionally provide more detailed information on
why the image is not a supported image.
- Validate the data from VendorCode if not null. Image validation must be performed before
VendorCode data validation. VendorCode data is ignored or considered invalid if image
validation failed. The function returns EFI_ABORTED if the data is invalid.
VendorCode enables vendor to implement vendor-specific firmware image update policy. Null if
the caller did not specify the policy or use the default policy. As an example, vendor can implement
a policy to allow an option to force a firmware image update when the abort reason is due to the new
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
non-functional should be encoded in the image itself rather than passed with the VendorCode.
AbortReason enables vendor to have the option to provide a more detailed description of the abort
reason to the caller.
@param[in] This A pointer to the EFI_FIRMWARE_MANAGEMENT_PROTOCOL instance.
@param[in] ImageIndex A unique number identifying the firmware image(s) within the device.
The number is between 1 and DescriptorCount.
@param[in] Image Points to the new image.
@param[in] ImageSize Size of the new image in bytes.
@param[in] VendorCode This enables vendor to implement vendor-specific firmware image update policy.
Null indicates the caller did not specify the policy or use the default policy.
@param[in] Progress A function used by the driver to report the progress of the firmware update.
@param[out] AbortReason A pointer to a pointer to a null-terminated string providing more
details for the aborted operation. The buffer is allocated by this function
with AllocatePool(), and it is the caller's responsibility to free it with a
call to FreePool().
@retval EFI_SUCCESS The device was successfully updated with the new image.
@retval EFI_ABORTED The operation is aborted.
@retval EFI_INVALID_PARAMETER The Image was NULL.
@retval EFI_UNSUPPORTED The operation is not supported.
@retval EFI_SECURITY_VIOLATIO The operation could not be performed due to an authentication failure.
