lib/igt_fb: Add support for testing of 16 bpc fixed point formats.
This is used to support testing the 16 bpc formats, e.g., via:
kms_plane --run-subtest pixel-format-pipe-A-planes
So far this was successfully tested on AMD RavenRidge with DCN-1
display hw. Ville also tested it against some of his patches for
16 bpc support on i915.
The new conversion routines are slightly adapted copies of the
convert_float_to_fp16() and convert_fp16_to_float() functions,
with the conversion math modified for float <-> uint16 instead.
