test(ivy): move content projection tests to acceptance (#30357)
Moves all manual `render3` content projection tests that use the `ɵɵelementProperty` to acceptance tests. Additionally a few other content projection tests were moved over to acceptance. Eventually we'll be able to move all remaining content projection tests to acceptance. PR Close #30357
