Add tab switch notification to the Mac plugin plumbing.

Using the new notification:
- Update plugin clip rect when it's not in a visible tab.
- Update plugin idle event rate when it's not in a visible tab.
- Switch the unfocus-on-tab-switch event to be based on the this new notification, instead of a browser-level broadcast.

Related changes:
- Stop sending redundant focus events to plugins.
- Send window activation to Carbon event plugins too, not just Cocoa.
- Now that plugins are getting window and tab de-focus events directly, remove the older hack to force all plugins to lose focus any window or tab loses focus.

BUG=29371, 32229, 30838
TEST=Flash should still only register keystrokes when it is in the active window+tab. Plugins in background tabs should use less CPU.
