Auto merge of #104527 - ferrocene:pa-more-licenses, r=pnkfelix

Add more license annotations

This PR updates the `.reuse/dep5` file to include more accurate licensing data for everything in the repository (*excluding* submodules and dependencies). Some decisions were made in this PR:

* The standard copyright attribution for files maintained by us is "The Rust Project Developers (see https://thanks.rust-lang.org)", to avoid having to maintain an in-tree `AUTHORS` file.
* For files that have specific licensing terms, we added the terms to the `.reuse/dep5` rather than adding SPDX comments in the files themselves.
* REUSE picks up any comment/text line with `Copyright` on it, so I had to sprinkle around `REUSE-IgnoreStart` and `REUSE-IgnoreEnd` comments.

The rendered `COPYRIGHT` file is available at https://gist.github.com/pietroalbini/efb81103f69596d39758114f3f6a8688.
