TST GH26807 Break up pandas/tests/io/pytables/test_store.py
This PR addresses xref #26807 for pandas/tests/io/pytables/test_store.py, which was more than 5000 lines before this attempt. I made a new directory pandas/tests/io/pytables/store/ to put all the new modules in. I tried to 1) get all the new modules below 1000 lines and 2) break it up in a somewhat logical way, but let's see if I succeeded in the opinion of the reviewer.

There were 194 tests in pandas/tests/io/pytables/test_store.py, and now there are 194 tests in pandas/tests/io/pytables/store so I haven't gained or lost any. One is skipped on my dev machine.

Correct. I made no changes at all to the tests - just moved existing ones to other classes & modules. looks good. can you merge master (small conflict), and show the before/after test count. ping when ready 273 tests in pandas/tests/io/pytables both before and after the changes thanks @moink
