Add support for setting OEM flags in the capsule header. As per the
UEFI specification, bits 0-15 of the flags member of the capsule
header can be defined per capsule GUID.
The oemflags will be used for the FWU Multi Bank update feature, as
specified by the Dependable Boot specification[1]. Bit
15 of the flags member will be used to determine if the
acceptance/rejection of the updated images is to be done by the
firmware or an external component like the OS.

The Dependable Boot specification[1] describes the structure of the
firmware accept and revert capsules. These are empty capsules which
are used for signalling the acceptance or rejection of the updated
firmware by the OS. Add support for generating these empty capsules.

While building a capsule, the GUID value of that specific image is to
be passed through the --guid command option to the mkeficapsule
tool instead of using one of --raw or --fit options, where the GUID
value passed through the command line option is the image GUID.
This renders the EFI_FIRMWARE_IMAGE_TYPE_UBOOT_FIT_GUID and
EFI_FIRMWARE_IMAGE_TYPE_UBOOT_RAW_GUID values superfluous. Remove the
--raw and --fit command line options as well. Also modify the
mkeficapsule man page to reflect this change.

The existing options, "--fit" and "--raw," are only used to put a proper
GUID in a capsule header, where GUID identifies a particular FMP (Firmware
Management Protocol) driver which then would handle the firmware binary in
a capsule. In fact, mkeficapsule does the exact same job in creating
a capsule file whatever the firmware binary type is.
To prepare for the future extension, the command syntax will be a bit
modified to allow users to specify arbitrary GUID for their own FMP driver.
OLD:
[--fit <image> | --raw <image>] <capsule file>
NEW:
[--fit | --raw | --guid <guid-string>] <image> <capsule file>
