mkeficapsule: Add support for setting OEM flags in capsule header
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.
