Ensure update methods of actions and reactive statements work with fine-grained `$state` by deep-reading them. This is necessary because mutations to `$state` objects don't notify listeners to only the object as a whole, it only notifies the listeners of the property that changed.

Add source map merging for preprocessors and get tests passing.
- fixed some issues around the `sources` array where they weren't calculated relative to the input correctly
- adjusted some CSS tests because due to our own CSS parser the AST is less granular, so there are less mappings now. Don't think this is a problem, but worth thinking about
- removed enableSourcemap but only log a warning, the reason this was introduced was to mitigate a bug in Vite which occured when having the source map inlined into the SSR'd output. Since SSR doesn't contain inlined CSS anymore (and if it did, we would omit the source map) the reason for which it was introduced no longer exists
- files without js mapping in it have no source mappings yet (originally added in Svelte 4 for #6092)
* rename $derived.call to $derived.by
* more replacements, plus a compiler error
* regenerate types

Relax the runtime error to only throw when you're passing a binding with an undefined value. This makes it possible to provide components in a way that can be used more flexibly while keeping the error to guard against the case that we want to avoid: a default value propagation up.
* fix: handle sole empty expression tags
When there's only a single expression tag and its value evaluates to the empty string, special handling is needed to create and insert a text node

* fix
* need this, too

Closes#9420.
This PR creates an $effect.pre (before beforeUpdate and an $effect (for afterUpdate) and, inside those, listen for all locally declared signals plus reactive props. This does mean that we need to link the locally declared signals to the component context (the reverse of the current behaviour, wherein we link the component context to locally declared signals).
fixes#10296
Also make sure to use the server export conditions when resolving Svelte imports from inside the server compiler output
