Auto merge of #26407 - mrobinson:animation-restyle-model, r=jdm

Have animations more closely match the HTML spec

These two commits do two major things:

**Have animations ticks trigger a restyle**: This corrects synchronization issues with animations,
where the values used in layout are out of sync with what is returned by `getComputedStyle`.

**Tick the animation timer in script according to spec**: This greatly reduces the flakiness of
animation and transitions tests.

Fixes #13865.
