Autoplay follow up

[darkdh]

1. play() video instead of reload when user click "Allow" from permission bubble (suggested by @bbondy)
2. Merge autoplay and sound into one site setting (suggested by @bridiver)
3. Add "allow muted video" option tracked in (Allow block audio only for autoplay, and make that the default #1088)
4. Improve patch of chrome/browser/content_settings/tab_specific_content_settings.cc
5. Default allow rules for popular sites tracked in (Whitelist some sites to not block autoplay by default #1089)
6. Handle cases like users specify different autoplay policy in about:flag (we currently use User gesture required as default but we respect users choices)
7. autoplay icon (cc @bradleyrichter)

Is default-allow for popular sites the right move?

[darkdh]

you can check Safari to see this whitelist behavior

@tomlowenthal that's what we do now so this is just for feature parity

Okay, but what if we did this instead and it was beautiful: https://twitter.com/potch/status/1024406683940843521

We already have this. Did you try 0.53.3 brave-browser?

[tildelowengrimm]

Just did. Sorry for the hassle!
