Does this belong in the ultimate ('OS!="android" and OS!="ios"') dep block,
since this will be views+cocoa specific (excluded on android/ios).

This should be views/cocoa independent. ChromeBubbleManager is the part
that's specific to views and cocoa.

Right, but it shouldn't be expressed as a dependency of the chrome browser ui
code on Android if it won't be used there. It shouldn't be compiled/linked into
Chrome on platforms where it's not used.
