Use a sane naming scheme for content setting bubble classes.

I'm renaming the platform-specific content setting bubble classes to the uniform naming scheme content_setting_bubble_{views,gtk,cocoa}.{h,cc}

XIB changes: Rename ContentBlockedBubbleController in ContentBlocked*.xib to ContentSettingBubbleController.

BUG=none
TEST=everything compiles
