Pre-check for 1.16.0 that supports C++20

[jdblischak]

Here is the pre-check PR for the future SOMA release that will support C++20. I followed my instructions in #246 (comment) to create the PR.

git checkout -b jdb/pre-check-cpp20-main

# Apply patch to support C++20
patch -p1 < .github/scripts/nightly/cpp20.patch

git commit -a -m "Support C++20" --author="XanthosXanthopoulos <[email protected]>"

@johnkerl once you have a candidate release ready to pre-check, we just need to update git_rev to point to that commit. You can either push directly to my branch (it's from my fork, so you'd have to add my fork as a remote), or you can simply share the SHA here and I can update the PR.

I had to manually remove the [ci skip] from the commit message body of my reverted commit, since it caused the entire PR to skip CI.

@jdblischak thank you -- this is fabulous!!!

TBD whether our next will be 1.15.8 or 1.16.0 -- requiring C++ 20 and GCC 13 is perhaps a "big enough change" to merit a 1.16.0. Let's keep this PR open for a bit until we decide what to call the next release, and when.

@jdblischak I used gh pr checkout 275 and updated the hash and the candidate tag -- thank you!

[johnkerl]

All green! Closing as per our established procedure.

As expected, this worked:

INFO (libtiledbsoma,lib/libtiledbsoma.so): Needed DSO lib/libspdlog.so.1.15 found in conda-forge/linux-64::spdlog==1.15.1=hb29a8c4_0

@johnkerl please include -DSPDLOG_LINK_SHARED=ON in recipe/build-libtiledbsoma.sh in the 1.16.0 update PRs
