pixdesc: add limited|full aliases for -color_range parameter
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
69aa7bf52bbd72444268a544c81d7643 /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
1ccb85d14a3dfecb22e625711587ba97 /tmp/full.y4m
```
Also ran fate.
```
$ make fate -j
