For the purposes of testing different EDID features, we need to generate more
and more complex EDID blobs (e.g. with audio support). However currently IGT
uses a macro-based system to generate EDIDs. This doesn't scale well and is
pretty inflexible.
This commit introduces a new little library to generate EDIDs. For now it can't
do more than the old macro. Future commits will extend the API.
The structures are mostly based on the Linux kernel code (drm_edid.h). Setters
have been added for convenience.
