Move transition-timing-function.html to WPT and deflake

The original test did not properly ensure that the style change would be
picked up after rendering the page. Thus, we might not see transition
animations. The test also relied on windows.internals, which does not
provide cross-browser support. Moved the test to WPT and switched to
using appropriate web-animation API calls. Dropped the webkit prefix
from the test. Finally, updated the expected target values. Two of the
values in the original test were off by 1, but matched the overly loose
tolerance. The updated version computes the expected value of the cubic
Bezier easing functions.

Note, this is one of 7 flaky tests associated with the bug. Next step is
to port the remaining tests unless WPT equivalents can be found.
