Bug 1362165: Add web platform test. r=gerald

Browse Source 
readyState is supposed to be updated during MSE's Initialization Segment Received and Coded Frame Processing algorithm.
Only then would the appendBuffer operation terminates by queueing the update/updateend events.

These tests ensure that loadedmetadata and loadeddata are fired first.
