misc_util: misc utils for UEFI

Daniel Lin created a new UEFI-centric project on Github last week called “misc_util”. Well, named, it contains miscellanous utilities, 3 for now:

* check_override: GUI script to show AptioV override folder and double click to open with Beyond Compare
* showdep: Show UEFI .depex section in human reable form
* pdtpacker: Pack up Intel ISS without MPDT header into a single PDT.binary with MPDT header because of RC will check the header
