feat(useAnimate): new function

[tolking]

Description

close #2077

I wrote some simple examples, source code

Additional context

I refer to the control option to add reactive option for the useAnimate function to return different structures.

• The control and reactive have different semantics while return different structures.
• I also thought about splitting into two functions, but I did not find anything similar in this project.

This function is great! Thanks, and sorry for the long delay.

I see that the reactive option is purely an addition, right? I refactored it a bit to make it always return those info, which I think fits more with VueUse's conventions.

Let's have it for now. If you have any other suggestions to make, feel free to open new PRs.
