This makes it possible to slow them down using dev tools, and overall ties the implementation more closely to WAAPI, which is good. Also fixes#12730 (all four cases, css, tick, css+tick, neither are now supported) and fixes#13019 (passed empty fallback object)

* fix: repair `href` attribute mismatches
The reasoning in #9662 turns out to be false: While it's true that the href would resolve to the same URL on the initial page, once you're doing a client-side navigation to a URL at a different depth, the relative path would now point to the wrong location. Therefore we need to repair href hydration mismatches

* fix: more robust handling of var declarations
- fixes#12807: state declared with var is now retrieved using a new `safe_get` function, which works like `get` but checks for undefined
- fixes#12900: ensure we're not creating another new scope for block statements of function declarations, which resulted in var declarations getting "swallowed" (because they were hoisted to the function declaration scope and never seen by our logic)
* simplify

The backing store variable of a $store read could be a variable that itself needs a transformer, which is why we need to make accessing the reads lazy

Also reserve a few attributes, which we may or may not use in the future

We need to allow mixing those within custom element components because in a future version of Svelte where we remove the Svelte-version of slots, we'll preserve slots as-is, and people should use those within their components. At the same time they should be able to make use of snippets for reusable blocks of code.
Also document that you should continue using slots within custom elements.
