feat(ivy): support queries with views inserted through ViewContainerRef (#24179)

Browse Source 
This PR tackles a simple case where ViewRef definition point (<ng-template>) is the
same as the insertion point (ViewContainerRef requested on the said <ng-template>).
For this particular case we can assume that we know a container into which a given
view will be inserted when a view is created. This is not true fall all the possible
cases so follow-up PR will be needed to extend this basic implementation.
