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.

the code to compose together the instance was getting a bit messy because we were trying to add stuff all in the same place if there was no script or one by one if there was one. I changed this a bit by using an insertion_point variable that we can set to then insert stuff sequentially.
Fixes#13390
There's pruning logic in a different place where all unused selectors are commented out. If all selectors are unused, the whole prelude is commented out, resulting in invalid syntax. This is a case that shouldn't happen, therefore simplify the whole "is used" logic to only look at the prelude.
- add a comment to lone script tags to ensure there's always a parent so we can synchronously call the replace function
- always call the replace function, not just on the first call
fixes#13378
