lib: extract igt_fb library
Stuff all the framebuffer creation, cairo and drm fourcc format handling in there. This gives us a very clear cut in the headers where igt_fb.c only needs to include igt_fb.h, and igt_kms.c includes both (well igt_kms.h pulls in igt_fb.h since we always need this). The aim here is to add api docs for igt_fb since that part of the kms library seems fairly stable already, while all the mode setting and iteration is still a bit in flux.
