[ty] Avoid unnecessarily allocating Union/IntersectionBuilder (#24036) ## Summary We have several places where we optimize the just-one-type case in order to avoid calling `UnionType::from_elements` or `IntersectionType::from_elements`. Rather than implementing this optimization ad-hoc at various call sites, implement it inside the two `from_elements` methods, so callers never need to worry about just calling them. This PR is perf-neutral, but removing the existing optimizations causes meaningful regression. This just consolidates those existing necessary optimizations so that all callers get them. This is not _purely_ a refactor, as passing a type through union/intersection building can unpack a type alias, but I consider that a neutral or positive change. There's no need to unpack an alias if we aren't actually unioning or intersecting it with anything. One downside of this change is that we have to repeat the fact that an empty union is `Never` and an empty intersection is `object` in a second place. But this is not a fact that is likely to change, so I think that's worth the optimization. ## Test Plan Existing CI.

[ty] Infer yield expression (#23796) ## Summary Infer yield and yield from expression using function annotation. Part of https://github.com/astral-sh/ty/issues/1718 Remaining part is checking return types, I'm planning to do that in a separate PR. All the remaining conformance tests are because of the return type checking. ## Notes Mixing Generator and Async Generator is allowed. ```py def async_returns_generator() -> Generator[int, int, None] | AsyncGenerator[int, int]: x = yield 1 reveal_type(x) return None ``` I was not sure if there's valid use case for this or not. But I found [this code](https://github.com/vippsas/zeroeventhub/blob/main/python/zeroeventhub/zeroeventhub/data_reader.py#L22) and [mypy](https://mypy-play.net/?gist=4293848a184dac5a7b49d3a7b5ed71c8) allows this. So I'm not doing any checks for this case. Just the normal logic that unions the types. [Pyright](https://pyright-play.net/?pyrightVersion=1.1.405&strict=true&code=GYJw9gtgBALgngBwJYDsDmUkQWEMogCmAboQIYA2A%2BvAoQFCiSyKoZY55QDihKhIMjFwAaKAEEAznBQBjXv0HCQ9egBNCwKGWlyqRGAFcQKSVTR8BQ3AAoAlFAC0APh6WluANqoYYn2IA5MH4AXSgAHwldeXdrEG8UX0xEkIAueihMqAAPKABeKDgkQgo1KABGDKyiUkoaREIbbLsqzINjFCgg-iA) rejects this. --------- Co-authored-by: David Peter <mail@david-peter.de>
