Benson Ma 66a2600b6a [T153220354] Fix header inclusions in c10 (#1541) (#101846)
Summary:
This is a re-attempt to land the iwyu header changes, by taking the diff from [PR 100304](https://github.com/pytorch/pytorch/pull/100304), and adding the bare minimal changes to make the diff build corectly in the internal builds.

X-link: https://github.com/fairinternal/pytorch3d/pull/44

- Re-work D45769819 to fix header inclusions in c10

Test Plan:
```
buck2 build --no-remote-cache mode/dev-nosan //caffe2/c10/...

buck2 build --no-remote-cache mode/dev-nosan //deeplearning/fbgemm/fbgemm_gpu/...

buck2 build mode/dev-nosan //vision/fair/pytorch3d/pytorch3d:_C
```
