[bshoshany-thread-pool] Updated to v3.4.0

[bshoshany]

• Changes comply with the maintainer guide
• SHA512s are updated for each updated download
• The "supports" clause reflects platforms that may be fixed by this new version
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

Thanks!

@bshoshany Note: I will be converting your PR to draft status. The above suggested changes are only recommendations. If you are willing to adopt them, please click "ready for review" after making the modifications. If you do not wish to make any changes, please click "ready for review" directly. That way, I can be aware that you've responded since you can't modify the tags.

Thanks! I accepted your changes, but now it's failing a check :(

I removed the line you indicated, but it's still failing a check - although maybe I didn't understand what you wanted me to change. Perhaps we should just revert to the original version? Thanks.

@bshoshany The CI error was reported because the SHA value is incorrect. After making the changes, you should run the command again to update the SHA: \vcpkg.exe x-add-version bshoshany-thread-pool --overwrite-version.

In the end I decided to just revert to my original version, since unfortunately I don't have more time to devote to this PR. I will incorporate the REF "v${VERSION}" trick next time I update the package. Thanks again :)
