In #48421 we removed all limits from apply_type, but that can lead to significant expression complexity which may be hard for subtyping to deal with. Try adding a heuristic size limiting constraint. Also do a bunch of code rearrangement and slight cleanup so that this change does not make the logic look complicated here. Solves #49127

Note that this can cause the existing severe performance problems for tests like LinearAlgebra/addmul to become even more severe. But some of my other recent PRs to fix the lowering issues that seem to be major causes of that will hopefully alleviate that particular issue.
