In edge cases it may happen that set_attributes is re-run before the effect is executed. In that case the render effect which initiates this re-run will destroy the inner effect and it will never run. But because next and prev may have the same keys, the event would not get added again and it would get lost. We prevent this by using a root effect.
The added test case doesn't fail for some reason without this fix, but it does fail when you test it out manually, so I still added it.

Deriveds where under certain conditions not detected as dirty correctly. The reason is that a transitive check_dirtiness call could update the flag of a derived, even if the condition doesn't ulimately result to true. That's why the check for "is now dirty" needs to be moved out of the inner if block.
Fixes#11481
This may also fix a yet undetected overfiring bug in the "is unowned" case because the previous inner "is now dirty?" check didn't take unowned into account.

We need to keep track of the component function similar to how we keep track of the component context, so that effects etc have the correct one associated
Ownership validation had a false positive when rendering a component as slotted content of another component. To fix this, #11401 did set the current component context to the context the snippet was declared in, not to the context it is rendered in. This was flawed because it means that component context was altered in a way that setContext/getContext failed because the parent chain was incorrect. This fixes that by introducing a separate global (dev time only) which tracks the component function the ownership needs.
fixes#11429
Instead of using types that declare whether or not a type is bindable directly as part of the property, we're introducing a new for-types-only field to `SvelteComponent`: `$$bindings`, which is typed as the keys of the properties that are bindable (string by default, i.e. everything's bindable; for backwards compat). language-tools can then produce code that assigns to this property which results in an error we can display if the binding is invalid
