more float constants: sqrt(5), 1/sqrt(5), ln(3)
rename EGAMMA to GAMMA

Adds constants discussed in #103883
I discuss why I prefer the variable name GAMMA in the issue but if a majority disagrees then I can change it back.

Would you be able to file an ACP for this so the API team discusses it? It's an issue template at https://github.com/rust-lang/libs-team/issues, should be pretty easy.

The ACP was accepted with changes, this PR will need to be updated rust-lang/libs-team#661.

This PR was rebased onto a different main commit. Here's a range-diff highlighting what actually changed.

Rebasing is a normal part of keeping PRs up to date, so no action is needed—this note is just to help reviewers.

@joshuarayton any reason you closed this? The ACP was mostly accepted, this just needs some easy changes to meet rust-lang/libs-team#661 (comment).

Sorry. When I tried updating the code, I wasn't sure how to stabilise EULER_GAMMA and GOLDEN_RATIO under their new name. I updated their name and thought the stabilisation process would be done someplace else before a release. Then when this PR became unmergeable because of #151164, I thought that was all done. I then closed this PR and deleted my fork. Now I realise that it wasn't finished because $\sqrt{5}$ and $\frac{1}{\sqrt{5}}$ aren't implemented. I have now forked again and made relevant changes in the more-float-constants branch. It won't let me reopen this pull request, saying 'The repository that submitted this pull request has been deleted.'.
