[c++/python] Updates for core 2.27

[johnkerl]

Issue and/or context: Key point here is test-unbreaks when someone points at dev of core which has some recent mods including TileDB-Inc/TileDB#5303

#3364

Changes:

Make unit tests pass when core is recent dev, e.g. TileDB-Inc/centralized-tiledb-nightlies#24

There is more to do on #2407 / [sc-51048] for Python and R both to incorporate new support for current domain in dense arrays.

Notes for Reviewer:

[johnkerl]

This includes #3179

I meant to:

• Get this merged to main
• Merge [python] Support for current domain on dense arrays #3179 to the new main

However I merged #3179 into this one :|
