Bug 1448700 [wpt PR 10171] - Web Animations: remove timing objects, a=testonly

Automatic update from web-platform-testsWeb Animations: remove timing objects

The upstream spec has removed the 'timing' objects and replaced them
with updateTiming/getTiming methods on AnimationEffect. It also removed
and renamed a few timing idl interfaces; see the bug for full details.

This CL also refactors the timing input parsing, aiming to make the
public TimingInput API match what the spec requires and not expose
other unnecessary methods.

See https://github.com/w3c/csswg-drafts/pull/2432 for the spec change.
