Rollup merge of #140874 - mejrs:rads, r=WaffleLapkin

make `rustc_attr_parsing` less dominant in the rustc crate graph

It has/had a glob re-export of `rustc_attr_data_structures`, which is a crate much lower in the graph, and a lot of crates were using it *just* (or *mostly*) for that re-export, while they can rely on `rustc_attr_data_structures` directly.

Previous graph:

Graph with this PR:
![graph_2](https://github.com/user-attachments/assets/1e053d9c-75cc-402b-84df-86229c98277a)

The first commit keeps the re-export, and just changes the dependency if possible. The second commit is the "breaking change" which removes the re-export, and "explicitly" adds the `rustc_attr_data_structures` dependency where needed. It also switches over some src/tools/*.

The second commit is actually a lot more involved than I expected. Please let me know if it's a better idea to back it out and just keep the first commit.
