REF/TST: resample/test_base.py
follow-on from #24377
xref #25197

in #24377, the `pytest_generate_tests` hook was used to parametrize the base tests over date_range, period_range and timedelta_range indexes.

to make it easier to understand the code and use less pytest magic, this PR uses a simpler approach of applying markers to the tests instead of having the test name ending in _all_ts.
