Reland: [shapedetection] Add some shapedetection tests

The original CL has been reverted because the test
external/wpt/shape-detection/detection-HTMLVideoElement-invalid-state.html
is flaky.

In the previous CL, the way to create a HTMLVideoElement with 'HAVE_METADATA'
state is wrong, because simply loading a video file its readyState should
be >= HAVE_METADATA during loadedmetadata event. Which is the reason of the flaky.

This reland CL leverages MediaSource API to precisely trigger a transition
to HAVE_METADATA state by invoking appendBuffer() with an initialization segment.

See relevant spec: https://w3c.github.io/media-source/#sourcebuffer-init-segment-received

Original change's description:

[shapedetection] Add some shapedetection tests

Cover following two checkpoints:

• If the ImageBitmapSource is an HTMLVideoElement object whose readyState attribute
  is either HAVE_NOTHING or HAVE_METADATA then reject the Promise with a new
  DOMException whose name is InvalidStateError.
• If the ImageBitmapSource argument is an HTMLCanvasElement whose bitmap’s origin-clean
  flag is false, then reject the Promise with a new DOMException whose name is SecurityError.
