fix(ivy): remove TNodeType assertion from `directiveInject` instruction (#33948)

The assertion that we have in the `directiveInject` instruction is too restrictive and we came across some pattern where it throws unnecessarily. This commit removes that assertion for now and more detailed investigation is needed to decide is we need to restrict the set of TNodeType again.

This commit also adds a test which triggered the TNodeType.View to come up in the `directiveInject` instruction, so it might be useful to avoid regressions during further refactoring.
