- shard runtime tests for better use of Vite's test parallelization
- merge custom element and other browser tests to run in one test suite and use esbuild in it
- on some setups only generate code output when test fails
Also swap out the require hook hacks with a less-hacky-but-still-somewhat-hacky loader for the Svelte files

Fixes#8284.
The problem is that the <slot> element is treated as an actual element, and for this purpose, we have to treat them as if they don't exist. More specifically, we treat all slot fallback children nodes on the same level as the slot's non-slot siblings.
Closes#6969
As discussed there, container query support is quite useful to add to Svelte as it is now broadly available with Firefox releasing support imminently w/ FF v110 this upcoming week (~Feb 14th). Chrome has had support since ~Aug '22. The central issue is that css-tree which is a dependency for CSS AST parsing is significantly lagging behind on adding more recent features such as container query support. Ample time has been given to the maintainer to update css-tree and I do have every confidence that in time css-tree will receive a new major version with all sorts of modern CSS syntax supported including container queries. This PR provides an interim solution for what Svelte needs to support container queries now.
Fixes#7152, see also #7288
--foo:; used to be an invalid CSS custom property value, while -foo: ; was valid. By collapsing the whitespace in these declaration values, we were breaking scenarios where an empty custom property was desired. The spec was updated to trim whitespace and treat these values identically, but Chromium browsers still treat --foo; as invalid. This was recently fixed and will be released in Chrome 99, but this would still be a good fix to maintain backwards compatibility.
