Implement a 'no graphics support' boot

This deliverable is to remove all images from the DXE portion of UEFI (Logo, low battery, too hot, etc), remove any graphics protocol drivers, and verify boot into Windows still works.

This task relies on the EC signaling to the TCON for thermal and power errors prior to removing the SOC from reset since UEFI will no longer be able to display those images.

We also need to consider OEMs that may have requirements such as color bars or status during development boot cycles or running things like the Shell at the factory. So, this removal should not hinder re-adding a GOP and drivers that display images or text.

Start by locating the DXE image handling and graphics protocol drivers, then trace how the EC signals the TCON before the SoC leaves reset. Verify that Windows still boots without UEFI graphics and that OEMs can later re-add GOP, image, or text-display support for development and factory workflows.
