[chromecast] Introduce cast_source_set

The main changes are in chromecast/chromecast.gni

The rest of the files were modified with these commands:

- Change source_set -> cast_source_set
git ls-files "chromecast/*.gn" | xargs sed -i 's/source_set(/cast_source_set(/g'

- Include chromecast.gni for any GN files missing it
git ls-files "chromecast/*.gn" | xargs grep -L '//chromecast/chromecast.gni' | xargs grep -l 'source_set' | xargs -L1 ~/src/scratch/add_line_after_first_comment.py 'import(' '"//chromecast/chromecast.gni")'

add_line_after_first_comment.py can be found under
chromecast/internal/tools
