fix(ivy): ng-content tags in re-inserted templates should walk declaration tree (#27783)

Browse Source 
This PR assures that content projection works if an <ng-content> tag is
placed inside an <ng-template> in one component and that <ng-template>
is inserted into a different component. It fixes a bug where the
projection instruction code would walk up the insertion tree to find
selector data instead of the declaration tree.
