refactor(ivy): inherently call ɵɵselect(0) (#30830)

- Refactors compiler to stop generating `ɵɵselect(0)` instructions
- Alters template execution to always call the equivalent of `ɵɵselect(0)` before running a template in update mode
- Updates tests to not check for or call `ɵɵselect(0)`.

The goal here is to reduce the size of generated templates
