meson: Add all, all_free (default) options for video-codecs option.

- Adds new 'all' value to the video-codecs option
- Adds 'all_free' value to video-codecs and sets
   it as default value for non patent-encumbered
   codecs, restoring the behavior for these codecs
   before existing as options in commit 7b22dd8bfd

Fixes: 7b22dd8bfd ("meson: add vp9 and av1 codec support options")
