[vcpkg baseline][opencv4] Add features to control hdf5 and tesseract dependencies, disable libiconv

[Kai Pastor (dg0yt)]

Potentially disruptive:

• Users must explicitly ask for feature hdf or text instead of contrib.
• Drive-by fix: disable uncontrolled libiconv dependency in contrib/wechat_qrcode.
  Fix openimageio:arm64-windows-static-md baseline regression. Cf. https://dev.azure.com/vcpkg/public/_build/results?buildId=123745&view=logs&j=4df292c1-f579-5a84-c7d0-98b54b894473 et al.
  (This is a change for system with iconv in libc. But for those systems users could still override the option via triplet. OTOH it would take at another extra feature to make libiconv an explicit option, controlling the LGPL dependency.)

Benefits:

• The new features are true capabilities, unlike contrib.
• Removes redundant/wrong encoding of hdf5/tesseract platform support from opencv4.
• Unblocks other capabilities from contrib for platforms excluded by hdf5 or tesseract.
• Enables vcpkg-ci-opencv=pass requirement in ci baseline for arm64 windows.

Skipping opencv in feature tests because it adds CI time without adding significant value: Each feature maps to a feature in opencv4. For opencv4, features are already tested separately (opencv4[core,<feature>]). But used as a dependency from opencv, default-features are added (opencv4[<feature>]), so the tests cannot share binary artifacts.

This is unexpected (vcpkg-ci-openimageio:arm64-osx):

I believe this is outdated.

[Billy O'Neal (BillyONeal)]

I think this will disable feature test for anything that depends on opencv as well?

[Kai Pastor (dg0yt)]

Maybe I have seen these other two skip lines too often, recently ;-)

[Billy O'Neal (BillyONeal)]

I'm not sure I understand but it seems ok now 🙃

Version DB was fixed

Thanks!
