We read the currently selected value from the FormatContext.
We don't change to lower case at runtime anymore but keep the warning.

This is because if you do the equivalent on the client using innerHTML, this is the effect you'd get.

Treat `<a href="" />` the same with and without `enableFilterEmptyStringAttributesDOM` in #18513 we started to warn and ignore for empty `href` and `src` props since it usually hinted at a mistake. However, for anchor tags there's a valid use case since `<a href=""></a>` will by spec render a link to the current page. It could be used to reload the page without having to rely on browser affordances. The implementation for Fizz is in the spirit of #21153. I gated the fork behind the flag so that the fork is DCE'd when the flag is off.

This implements all the DOM bindings parts as far as I know (except the reactroot attribute). I can't run it against our test suite yet. But I carefully ported everything I could.
There's only one breakage I decided to do. We don't force lower case HTML tags before comparing them. This means that special cases like
<select />,<textarea />etc. don't work if you use a different case. We warned about this before and warn about it after, so shouldn't matter.I did a very different structure from what we've done in the DOM bindings before though.
A problem with how we used to do it is that the logic is spread out into a lot of different concepts. This causes a lot of extra checks for each element because we check those things over and over. It also leads to unnecessary checks. A lot of the helpers check things like
== nullover and over or they overcheck because in that context it can never happen.Instead of a bunch of
isSomething(...)helpers. I structured it fully based on a switch over each kind of value once and from there the code flow determines what to do next.The structure is something like this:
First we switch on the type, then we loop over each property, we switch over the property name to find special cases, then we switch over the propertyInfo and finally the value type and that determines what we do.
So the goal is that we only check each of these once along that path.
All special cases are encoded along with that specific element type. This ends up needing to fork the loop. So there's a lot of duplication there. This is controversial because if you make a change to these things you have to replicate them. However, I've noticed subtle little issues because we don't consider how each special case applies to each tag. So this is actually a benefit. It's also better for perf.
Large switches might not be better than Map of Functions depending on VM but that's something we can automate if needed if it's expressed as a simple switch.
