[YouTube] Age-gate bypass implementation (#575)

Browse Source 
* Calling the API with `clientScreen=EMBED` allows access to most age-gated videos - discovered by @ccdffddfddfdsfedeee (https://github.com/yt-dlp/yt-dlp/issues/574#issuecomment-887171136)
* Adds clients: (web/android/ios)_(embedded/agegate), mweb_embedded
* Renamed mobile_web to mweb

Closes #574

The following extractors use this feature:
* **youtube**
* `skip`: `hls` or `dash` (or both) to skip download of the respective manifests
* `player_client`: Clients to extract video data from - one or more of `web`, `android`, `ios`, `mobile_web`, `web_music`, `android_music`, `ios_music` or `all`. By default, `android,web` is used. If the URL is from `music.youtube.com`, `android,web,android_music,web_music` is used
* `player_client`: Clients to extract video data from - one or more of `web`, `android`, `ios`, `mweb`, `web_music`, `android_music`, `ios_music`, `web_embedded`, `android_embedded`, `ios_embedded`, `web_agegate`, `android_agegate`, `ios_agegate`, `mweb_agegate` or `all`. By default, `android,web` is used. If the URL is from `music.youtube.com`, `android,web,android_music,web_music` is used. If age-gate is detected, the `_agegate` variants are automatically added.
* `player_skip`: `configs` - skip any requests for client configs and use defaults
* `comment_sort`: `top` or `new` (default) - choose comment sorting mode (on YouTube's side).
* `max_comments`: maximum amount of comments to download (default all).
