[a11y] Adding reduce motion logic to LottieAnimation for compose usage (#2542)

Our changes in #2536 didn't work for `LottieAnimation` in compose. While LottieAnimation does use LottieDrawable, it has it's own animator and draws on canvas directly. 

This PR addresses that issue by making some logic of reduce motion readable outside LottieDrawable and consuming that logic in `LottieAnimation` 

I tested this by adding a sample lottie file with reduce motion marker locally, see the attached video.
