Fix flakiness in animation tests

Browse source 
1. When updating the animation timeline, ensure that nodes that are
   animating are marked dirty, if necessary, so any style queries will
   force an layout flush.
2. Disable the problematic transition test suites, as they are in Gecko.
   These suites often fail when Servo is so overloaded that it cannot
   deliver frames fast enough to get more than two samples during the
   animation lifecycle.

Fixes #28334.
Fixes #26435.
Fixes #21486.
