[ci] Add MacOS job to test shared object copying

[jdblischak]

Issue and/or context:

• Follow up to [python] Do not copy libtiledbsoma.so into package_data if it already exists #1937
• Linked Issue: [ci] dylib-copy logic appears to be broken on MacOS #2210

Changes:

Expands SO copying pipeline to include a macOS job

Notes for Reviewer:

I have good news and bad news. The good news is that I added a macOS job, and its behavior is correct! The bad news of course is that this means it doesn't explain the feedstock failures where the macOS builds fail to find the shared objects.

I suspect this is because the feedstock is still using the older setup.py with the flag --libtiledbsoma (script). This was required pre-#1937. However, now that #1937 has been merged, we can now upgrade to the more modern alternative:

export TILEDB_PATH=$PREFIX
export TILEDBSOMA_PATH=$PREFIX
$PYTHON -m pip install --no-deps . -vv

update: replaced jinja2 {{ PYTHON }} (for use in meta.yaml) with $PYTHON (for use in separate build script)

See also #2219 for tracking

Has anyone seen this before? I can debug but am already debugging multiple things simultaneously in an attempt to unblock multiple teams, so I thought I'd crowdsource first ...

I'm not convinced this is urgently needed in the branches
