Merge #8716

8716: Replace `memmap` with `memmap2` in `proc_macro_api` r=edwin0cheng a=memoryruins

#7522 did the same for `proc_macro_srv` before this usage of `memmap` was introduced to `proc_macro_api` in #6822 .

Something like [`cargo-deny`](https://github.com/EmbarkStudios/cargo-deny-action) could help prevent specific crates (and versions, licenses, etc) from being introduced into the crate tree, but that's unrelated to this pull request.
