DEPR: remove some more Int/UInt/Float64Index from tests
Progress towards #42717, one easy step at a time... 

There are still some places that have these indexes, but maybe easier taking these things in steps.
pandas/tests/indexes/test_base.py::TestIndex::test_reindex_doesnt_preserve_type_if_target_is_empty_index_numeric I’ve updated the PR. thanks @topper-123
