Pawel Kozlowski 91a161aa13 refactor(ivy): simplify logic of projectable nodes insertion (#29008)
This commit removes code duplication around projectables nodes insertion.
It also simplfy the overall logic by using recursive function calls instead
of hand-unrolled stack (we can always optimise this part if needed).
