The other part of #13395
This implements scoping for selectors inside `:not(...)`. The approach is almot the same as for `:is/where(...)`.
This is a breaking change because people could've used `:not(.unknown)` with `.unknown` not appearing in the HTML, and so they need to do `:not(:global(.unknown))` instead.
While implementing it I also discovered a few bugs, which are fixed in this PR:
- `foo :is(bar baz)` wasn't properly handled. This selector can mean `foo bar baz` but it can also mean `bar foo baz` (super weird, but it is what it is). Since our current algorithm isn't suited for handling this, we just assume it matches and scope it. Worst case is we missed a prune
- `bar` in `:global(foo):is(bar)` was always marked as unused, even if it matched
The main part of #13395
This implements scoping for selectors inside `:has(...)`. The approach is to first descend into the contents of a `:has(...)` selector, then in case of a match, try to match the rest of the selector ignoring the `:has(...)` part. In other words, `.x:has(y)` is essentially treated as `x y` with `y` being matched first, then walking up the selector chain taking into account combinators.
This is a breaking change because people could've used `:has(.unknown)` with `.unknown` not appearing in the HTML, and so they need to do `:has(:global(.unknown))` instead

- make sure to not overfire before/afterUpdate
- make sure to not fire mutable sources when they were mutated
- only show deprecation warning when in runes mode to not clutter up console (this is in line with how we made it in other places)

fixes#13270 by resetting the has_call boolean to false to style/class attributes, which means we're not creating a separate template effect for the attribute, instead they're added to the common template effect in which style/class directives are also added to later
Fix a bug where play/pause events may never be added to the media element. Also simplifies the logic by making it an effect instead of a render effect

* feat: enable snippets to fill slots
This allows people to use snippets to fill slots. It is implemented in the same way the default slot interop is already implemented, by passing a boolean to the hidden `$$slots` object, and using that at runtime to determine the correct outcome. The impact on bundle size is neglible.
By enabling this, we can enhance our migration script to always transform slot usages (including `let:x` etc) to snippets. This wasn't possible before because we couldn't be sure if the other side was transformed to using render tags at the same time. This will be part of #13419. This is important because currently the migration script is transforming `<slot />` creations inside components, but since it's not touching its usage points the migration will make your app end up in a broken state which you have to finish by hand.
This is a reduced alternative to, and closes#11619, which was also enabling the other way around, but that is a) not as necessary and b) more likely to confuse people / break, because it only works if your render function has 0-1 arguments.
* unused
* ditto - annotation is redundant
* couple of drive-by consistency tweaks
