Split up pandas/tests/io/pytables/test_store.py into smaller modules

[moink]

pandas/tests/io/pytables/test_store.py is more than 5000 lines long, which is pretty long for a test module. It would be good to break it up into smaller, logical pieces, each in its own test module.

Came out of PR 38609.

OT: @moink love to split this file up: pandas/tests/io/pytables/test_store.py in a separate PR :->
