Move 'export_trait_data' to 'gn3.db.traits' module

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* gn3/db/traits.py: Move function `export_trait_data` here
* gn3/heatmaps.py: Remove function `export_trait_data`
* tests/unit/db/test_traits.py: Move function `export_trait_data` tests here
* tests/unit/test_heatmaps.py: Remove function `export_trait_data` here

  Function `export_trait_data` more closely corresponds to the traits and is
  used in more than just the `gn3.heatmaps` module. This commit moves the
  relevant code over to the `gn3.db.traits` module and also moves the tests to
  the corresponding tests modules.
