feat(tiny-transition): add LaggedBoolean

[hi-ogawa]

Inspired by the discussion on solid createPresense PR,

• Proposal: presence solidjs-community/solid-primitives#414 (comment)
• Refactors prensence package to SM implementation solidjs-community/solid-primitives#437

this adds a way simpler way of implementing transition.
The advantage is its simplicity where the library just provides "lagged" boolean state without managing DOM by itself.

idea

// animation in each direction requires two intemediate steps
//   false --(true)----> enterFrom --(next frame)--> enterTo  ---(timeout)-> true
//         <-(timeout)-- leaveTo   <-(next frame)-- leaveFrom <--(false)----

todo

• explicitly transition enterFrom -> enterTo?
  • this turns out to be more tricky to counter against react scheduling anyways. so let's reject this idea... 812c4fa
• can we rewrite Transition component based on this?

Overall, I'm not sure which is simpler when it comes to actually implementing general Transition component.
Probably this "lagged" value idea could be partially applied as a refactoring for the original TransitionManager, so maybe that's what I should go for...
