[Media Router] Remove MR FeatureSwitch's dependency on EAR.

The ExtensionActionRedesign field trial	expires after M51, and the
feature is already enabled by default. We should remove MR's dependency
on it.

Also, remove media_router_with_cast_extension FeatureSwitch as it's no
longer used.

This will need a merge, yes?

Yes, unless the branch hasn't been cut yet :)

Supposedly that was yesterday, but maybe we get lucky.  :)

Looks like it didn't make it into 52. :(
