qhull: add libqhullcpp component, add v8.1-alpha4

[valgur]

Summary

Changes to recipe: qhull/cci.20231130

Motivation

The qhull recipe currently does not export the libqhullcpp component, which is required by:

• cilantro: cilantro: new recipe #24528
• Open3D: https://github.com/isl-org/Open3D

I also added the latest head commit version to the recipe, since the development version includes a few useful changes, such as qhull/qhull#76 (thanks, @SpaceIm!).

Dropped v8.0.0, which is redundant to v8.0.1 and not used in any recipes.

Details

The cpp component is only available with the newly added version since I did not want to modify the existing patches.

Like the reentrant option, the cpp component is always built, but only exposed in package_info() when the option is enabled.

I had to re-enable the building and installing of the non-reentrant shared C library for backwards compatibility in the latest version.

• Resolves [question] Why is libqhullcpp excluded from all qhull packages? #16321
• Resolves [request] qhull/8.0.2 #13955 (presumably)

cilantro builds fine locally with an unvendored libqhullcpp library after these changes: valgur@b73a6bc

[SpaceIm]

Would it be possible to ask upstream a release in order to avoid a custom cci version?

This would be ideal @SpaceIm @valgur :)

@valgur @SpaceIm did you have some time to request for a semantic release schema at upstream? https://github.com/qhull/qhull/issues?q=sort%3Aupdated-desc+is%3Aissue+is%3Aopen

[valgur]

@perseoGI I asked and they kindly created a new pre-release: qhull/qhull#128 (comment)
I've already updated the recipe accordingly.
