Add extra mouse event handling

[rhaskia]

The following events now work with attributes:

• oncontextmenu (no actual context menu support)
• ondblclick
• onmouseover
• onmouseout
• onmouseleave
• onmouseenter
• onscroll
• onwheel

I did move the actual scroll handling code into handle_scroll, but it means redraw happens on every wheel event now, which is not ideal.

Fixed those issues with this newest commit, although the Instant is still where it was initially

I've left comments on a couple of important-but-trivial nits. And clippy/rustfmt need to be fixed. Other than that this it looking pretty close now?

Okay I'm not too sure why running cargo clippy on my machine didn't show that issue

You may need to run cargo clippy --workspace (aliased as just clippy if you have just installed) rather than just cargo clippy

Is there anything else you're still planning to do with this PR (it's still marked as a draft)?

The only thing I'm currently tracking is the extra request_redraw here: https://github.com/DioxusLabs/blitz/pull/304/changes#diff-d876680524cf67ed80f5091cadf5decf8ce9eef1842b8d827fc9c849ff1d037fR404

Yeah nothing else, I must have missed that extra redraw. I'll remove it and change the PR from draft.
