Add support for generating capsules through a config file. Multiple capsules can be generated through a single invocation of the mkeficapsule tool, where the capsule parameters are fetched from the config file.
The format of the config file pretty similar to the one used by the capsule generation tool in EDKII.
The functionality is enabled on the sandbox variant and the EFI capsule update test is now configured to generate the capsules through a config file. The sandbox_flattree variant generates capsules through binman, thus covering both the paths.
This is a rebased version of the earlier patch series that was sent to the mailing list [1]. That series was not getting merged as Simon had asked for generation of capsules as part of the sandbox platform build. Those patches have since been merged. Moreover, there has been adoption of the capsule generation logic by TI platforms as well, so that should address the concern which Tom had about it's usage.
These patches are more of a step in the direction of adding support for generation of a multi-payload capsule. There has been a request for it's support for a platform [2].
