[wavpack] Update to 5.7.0

[CrSjimo]

Update Wavpack to 5.7.0

• 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.
• When updating the upstream version, the "port-version" is reset (removed from vcpkg.json).
• 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.
