vo_gpu: vo_gpu_next: support --icc-3dlut-size=auto
And make it the default. In libplacebo, this uses internal heuristics to
pick a good size based on the actual ICC characteristics. This is
significantly less wasteful than always generating a 64x64x64 3DLUT (the
old status quo).
In vo_gpu, for simplicity, just default to 65x65x65. Note that this
provides slightly better accuracy than the old default of 64x64x64 for
technical reasons, and matches what libplacebo defaults to for typical
display profiles.
