Automatic update from web-platform-tests FileAPI: Add more WPT for Blob read methods. This change adds 3 new tests: 1. Make sure that garbage collection of the Blob will not break consumption of it's readable stream. 2. Make sure that concurrent reads via the text() method work. 3. Make sure that concurrent reads via the arrayBuffer() method work.
