Platforms/AMD/Overdrive: add signed capsule update support
Wire up the various modules and boilerplate configuration snippets
to implement signed capsule update for AMD Overdrive. Note that this
uses the insecure default key.
The secure firmware on this SoC does not implement warm reboot, so we
cannot support capsules that persist across reset. Instead, the capsule
may be installed using CapsuleApp (from MdeModulePkg), from the UEFI
Shell prompt.
