util: factor out and optimize C8 SMPTE color LUT
The color LUT for the SMPTE pattern in indexed mode contains 22 entries,
although only 13 are non-unique.
Reduce the size of the color LUT by dropping duplicate entries, so it
can be reused for formats supporting e.g. 16 colors. Rename the
function util_smpte_c8_gamma() to util_smpte_fill_lut(), and its first
parameter size to ncolors, to match their actual use.

v5:
- Add Reviewed-by,
v4:
- Rename util_smpte_index_gamma() to util_smpte_fill_lut(), and its
first parameter from size to ncolors,
- Move smpte_color_lut[] down,
- Kill FILL_COLOR() macro,
- Add and use EXPAND_COLOR() macro,
v3:
- Add Acked-by,
v2:
- Factor out smpte color LUT.
