igt_kms docs are just skeleton and also added igt_fb to make sure the
linking works correctly.
Next up: Actually documenting igt_fb.
Also fix that depency spelling fumble I've copied around to a few too
many places.

Shorter and more in line with our general igt_ prefix for everything
which isn't somehow intel or i915-gem or otherwise hw specific - these
helpers here are all fully generic framebuffer handling functions
based on kms + cairo.
Well, the actual buffer alloc is done with i915 gem, but meh ;-)
Two special cases:
- bpp_depth_to_drm_format and drm_format_to_bpp completely lacked
prefixes, so just add igt_.
- write_fb was a bit misleading given that we have gem_write for
uploading to buffers. Rename that to write_fb_to_png to make it
crystal clear what this thing does even without looking at docs.

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.
