[next] deopt spreads in DOM

[titoBouzout]

It deopts spreads, aka spreads should work the same as in JavaScript native.

It fixes:

• being able to override specific props on:* with ...props override not working solidjs/solid#2520
• props order is respected inconsistent errors with order of props (or w/ spread) for an input type=file solidjs/solid#2532

Notes:

• There may be some possibility for optimization. But I prefer if this works the same as native first, because if not we introduce behaviour that we cant change, (the reason we cannot merge this fix in solid v1). If this works the same as native, then we can see how to optimize it keeping that behaviour in mind.
• Same should be done in SSR
• use: and ref arent merged, future of both seem to be undecided.
• It also overwrites duplicated attributes <div c="1" c="2"/> discards c="1" producing <div c="2"/>

Problems:

• merging ref and use seems challenging

Also merged this <div c="1" c="2"/> that produces <div c="2"/>, to make it consistent.

I am currently being blocked by use:, I am proposing to just use namespaced refs instead. https://discord.com/channels/722131463138705510/1435384712443990096
