[python3] Some patches up for discussion

[Neumann-A]

• [?] 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.

The vcpkg team (@dan-shaw @vicroms @JavierMatosD @ras0219-msft and I) discussed this today.

@ras0219-msft points out that in a vcpkg context we can add the bin directory of the host triplet to the %PATH%, so the add_search_path is only relevant to external-to-vcpkg callers. That makes the goal here somewhat suspicious. "We are not yet opening the can of worms that means becoming an application deployment platform, and that includes Python."

But we acknowledge that we as a team have a big blind spot in our understanding of the python / plugins ... situation. We probably need a better understanding of what you're trying to do here before pceeding.

Robert also points out that we could solve the package ownership problem by creating ports that own just the copy from bin to the right plugins place. (That isn't to say that we want to do that, just pointing it out for the sake of discussion)

the problem is that python doesn't care about PATH anymore.

Worst case scenario would mean an extra port for every port in vcpkg (just for python).

(I also tried to embed add_dll_directory in init statements however if you start deploying pythons scripts and the path being added becomes invalid you get a hard error. )

@Neumann-A
Do you want to continue this discussion? If not, I'll remove the requires:discussion tag and convert to draft.

[Neumann-A]

Yes this is still up for discussion
