Support running WebGL in its own thread or on the main thread.
This is the final missing piece to support WebGL in ANGLE on Windows. ANGLE doesn't support multiple GL contexts on separate threads using the same underlying Direct3d device, so we need to process all GL operations for WebGL on the same thread as the compositor. These changes try to retain enough flexibility to support both approaches so we can get WebGL working on Windows ASAP.

There are a few canvas2d-related dependencies that haven't updated, but they
only use euclid internally so that's not blocking landing the rest of the
changes.
Given the size of this patch, I think it's useful to get this landed as-is.

Added the appropriate attribute and setters. Included a Timer struct with a `Drop` function to set this value to zero in error cases. Set the value to `responseEnd` on success. Eliminated tests that now pass.
