Register PerformanceObservers with the Performance object.
When new PerformanceEntries are created (Mark and Measure
right now) check them against observers.

Give PerformanceEntry a convenience enum for easy comparison
and to know if it is one of the built-in known types (which the
PerformanceObserver API takes into account).

- TypeErrors on observe bad behavior
- Completely replace types filter on observe
- Handle register and unregister
- Handle calling the callback

Update these to return the entry so it can be passed on to
any interested PerformanceObservers.
