As part of FW-2832, the team would like to swap out usages of the any
type for stronger types.
## What is the new behavior?

- `scrollToTop` doesn't return anything, so I added the `void` return
type

- `animation.effect` is a type of
[AnimationEffect](https://developer.mozilla.org/en-US/docs/Web/API/Animation/effect).
One of the more common types of effects is a `KeyframeEffect`. However,
TypeScript doesn't know which specific type of AnimationEffect we are
using, so I cast `animation.effect` as KeyframeEffect where appropriate.
- I also added `!` to places where we know the effect and other
properties are always defined (since they run after the web animation
has been constructed)
- Added stronger types to the internal to/from/fromTo functions (the
public facing type improvements are in
https://github.com/ionic-team/ionic-framework/pull/28334)

- `getRootNode` can return multiple types of objects, so I cast it to
the specific types that we work with in `isFocused`.

- Added the "Animation" type and resolved related errors once we had
stronger types

- Made heavier use of the `T` generic
- Once we know `node` is an Element (`nodeType === 1`) we manually cast
the element as `T`

- The focus visible utility is an internal utility, but it was lacking
an interface, so I added one.

- Removed unneeded HTMLElement casting
- Added `!` since we can assume the selected elements are defined with
the refresher
- Added documentation as to why casting `referencEl.style` as `any` is
something we need to keep.

- Avoided the Event naming collision by using globalThis
