Debloat channels.cr into multiple files (#2225)
Cherry picked from ui overhaul branch with a few modifications:
- channel folder is renamed to channels
- parsing for channel home and featured channels are removed due to
lack of infrastructure from other commits
(cherry picked from commit 44d18b8e14)
