fix(ivy): pass `schemas` field to nested views (#31913)

Prior to this commit, the `schemas` configuration was applied to top-level view only. That leads to problems when using unknown props with elements inside nested views (for example generated as a result of *ngIf). This commit passes `schemas` information down to nested views to make sure that all the checks are consistent.
