[animation worklet] Add tests for fill mode behavior

Previously upon setting the local time beyond its duration we assumed
the behavior should be the same as we set it to the end point. However,
it's only true if the effect has fill mode: fowards specified. Otherwise
the animation should be deactivated. The expected behavior for the test
is updated.

Added a new test to cover the animation behaviors with fill modes.
