Remove non-invertible-transform-animation.html

The test added in https://crrev.com/911926 is failing on Safari:
https://staging.wpt.fyi/results/css/css-animations/non-invertible-transform-animation.html

This test only covered the behavior change in https://crrev.com/911926
when run manually because any runs of the lifecycle, such as the raf
run at the end of the test, would hide the bug. The test was re-written
using web animations which should pass reliably on Safari, but that
approach hides the original bug when running the test manually. Because
the WPT test is of minimal value, and the behavior change is tested via
a unit test, this patch just removes the test.
