### Rationale for this change
Pandas has deprecated certain aspects of `.values` (when it looses
information), which our pandas->pyarrow conversion currently relies upon. So
updating that code path to avoid this usage.
### What changes are included in this PR?
Removed usage of `.values` for the deprecated cases (period, interval,
datetimetz). In the custom `get_values`, we already avoided this for period and
interval, added a special case for converting datetimetz to a numpy array. And
ensured that other cases were we did a direct `.values` goes through this
`get_values` helper.
### Are these changes tested?
Yes, I added more tests first to ensure full coverage of all cases that
might run into the deprecation (e.g. the `Schema.from_pandas(df)` or
`pa.array(EA)` with period/datetimetz dtypes were not currently covered)
### Are there any user-facing changes?
No
### Was AI used for this PR?
No
