[cudnn] Fix cudnn dlls

[Olli1080]

This fixes that dlls won't be installed under windows when using TARGET_RUNTIME_DLLS generator expression in cmake.
The cause is a misspelled variable.

• 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.

I've found another edge case.
When copying cudnn into the cuda installation the path for the dlls is located at ../bin relative to the includes.
But when using the installer the include and bin directory are augmented by a folder with a cuda version. (e.g. include/12.6/; bin/12.6/

Tagging this team review on account that we don't allow find modules in the repo. I know this is already the status quo but given that this is the ports 15th revision, these are substantial changes to the find module, and FindCUDA.cmake is deprecated, I'm not exactly sure how to proceed here.
