[all components] Fix forwarded ref types

[atomiks]

• I have followed (at least) the PR section of the contributing guide.

This loosens or restricts the type of the ref for some components

Some rules:

• Non-button <div> elements should not be polymorphic (as in rendered as another tag, not replaced with a same-tag component), so these have strict HTMLDivElement
• Button <div> elements (e.g. composite items) can be polymorphic (e.g. rendered as an anchor tag), so use HTMLElement
• <Tooltip.Trigger> could be a non-HTML element (e.g. using SVG elements), so I've replaced instances of Element with HTMLElement where applicable, except for <Tooltip.Trigger>, where I made any stricter

---

This doesn't solve event.currentTarget typesafety in event handlers, yet. Also, some button components which are unlikely to be polymorphic (but technically allow it via nativeButton={false}) still use strict HTMLButtonElement instead of HTMLElement. Changing them to be looser could be ok, if worth it.

I'm wondering if we can/should enable non-HTML triggers for more components (think SVG buttons) as a follow-up (or if there's community demand). This would require adding a couple of conditions in focus management logic (as focus is not available in SVG elements).
