BLD/REL: add libspatialite to the wheels

[theroggy]

This PR:

• Add libspatialite as a gdal requirement so the wheels include libspatialite.
• Add a test to test this. To make sure the test actually works I added that it failed in this temporary PR: TST: check if test_spatialite_available test actually fails for wheels without libspatialite #580

Would it help to include libspatialite without freexl?

Yes, good idea: freexl is not needed for our use!

I'll give it a try.

A little bit different. Add libspatialite as a top-level dependency, with default-features: false.

vcpkg linux logs are still reported to be in /opt/vcpkg/buildtrees - this is not what is uploaded in the next step.

Thanks for having a look! I'm not a specialist at all in this, so much appreciated!

I only made the change in one of the 3 linux containers/builds (manylinux_2_28_x86_64-vcpkg-gdal), so sorry for the confusion. I now changed it in all three...

But, the log files are not found anyway...

I wondered if it has something to do with paths in the container versus local paths, so I tried copying the files first to a local path,, but I don't seem to get that working either :-(...
