🚚 Move CellxGene Curator from cellxgene-lamin here

[falexwolf]

Is part of a sequence of PRs that refactors the curators:

• 🚚 Move PertCurator from wetlab here and add CellxGene Curator test #2408
• ✨ Schema-based curators: DataFrameCurator #2388

This PR merely moves code without yet refactoring it.

It moves the CellxGeneCurator from cellxgene_lamin here and it moves the SpatialDataCurator from the separate file curators._spatial.py into curators/__init__.py.

This is to prepare a joint refactor of all Curator classes.

See the corresponding PR in cellxgene-lamin:

• 🚚 Move Curator to lamindb cellxgene-lamin#120

Why don't we split the gigantic __init__.py for curators?

Why don't we split the gigantic init.py for curators?

To prepare a refactor. And I find it much easier to enforce consistency if there is one file with a couple thousand lines of the same class over and over than this being spread out across different fiiles.
