Pawel Kozlowski bbdea96a66 refactor: remove import circular dependencies (#20855)
This PR fixes a circular dependency among those files in Renderer3:
`query` -> `di` -> `instructions` -> `query` -> ...

Looking at the above dependencies the `di` -> `instructions` import is
a problematic one. Previously `di` had an import from `instructions`
since we can known about "current node" only in `instructions`
(and we need "current node" to create node injector instances).

This commit refactors the code in the way that functions in the
`di` file don't depend on any info stored module-global variables
in `instructions`.
