pixdesc: add limited|full aliases for -color_range parameter

Browse Source 
Aliases are also used in scale and zscale filters.

Tested:
```
$ ./ffmpeg -hide_banner -y -i ~/src/media/images/y4m/lena.490x490.y4m  -pix_fmt yuv420p -color_range unknown /tmp/unknown.y4m
...
$ md5sum /tmp/unknown.y4m

$ ./ffmpeg -hide_banner -y -i ~/src/media/images/y4m/lena.490x490.y4m  -pix_fmt yuv420p -color_range tv /tmp/tv.y4m
...
$ md5sum /tmp/tv.y4m

$ ./ffmpeg -hide_banner -y -i ~/src/media/images/y4m/lena.490x490.y4m  -pix_fmt yuv420p -color_range pc /tmp/pc.y4m
...
$ md5sum /tmp/pc.y4m

$ ./ffmpeg -hide_banner -y -i ~/src/media/images/y4m/lena.490x490.y4m  -pix_fmt yuv420p -color_range limited /tmp/limited.y4m
...
$ md5sum /tmp/limited.y4m
5c1c8759708ff6b25dd8a660da5200e7  /tmp/limited.y4m

$ ./ffmpeg -hide_banner -y -i ~/src/media/images/y4m/lena.490x490.y4m  -pix_fmt yuv420p -color_range full /tmp/full.y4m
...
$ md5sum /tmp/full.y4m
