[vtk]: Convert dependencies into default features

[DownerCase]

Moves multiple previously mandatory dependencies to be default features instead. This was inspired by, and builds upon, @bansan85's work on #39511 to have vtk[core] pull in much less dependencies.

Everything is added as a default feature because the dependencies are required for things in the "Standalone" or "Rendering" VTK groups which the portfile has enabled (ie: VTK_GROUP_ENABLE_StandAlone=YES). So I take that as the "expected functionality".

This could be taken further but I was focused on value-for-effort and seacas was my main target for making non-strictly-required.

I've tested many configurations (if only on Windows) but if anything has problems it'll probably be from paraview or rtabmap; which I was not able to test properly because... they're huge.

• 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.
