Automatic update from web-platform-tests
ElementTiming and LargestContentfulPaint: add more redirect tests

This CL adds more tests for Timing-Allow-Origin checks in ElementTiming
and LargestContentfulPaint with multiple redirects. Before, we had tests
for:
* Single cross-origin response with a TAO header (image-TAO.sub.html).
* Multiple redirects, with '*' TAO header (multi-redirect-image.html).

This CL renames the latter to be more descriptive and adds:
* Same-origin redirect tests (should pass without TAO headers).
* Multi-cross-origin redirect tests with various TAO header values.
