fix: prevent ownership validation from infering with component context

[dummdidumm]

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
