POC/DEPR: infer time objects to ArrowDtype[time]
xref #52711 this is what I have in mind for how we would deprecate the current inference behavior with a sequence of `datetime.time` objects.  We would allow opting-in to the future behavior with `pd.set_option("future.infer_time", True)`.

I plan to update this PR to also deprecate returning object dtype from the `time` and `timetz` properties in the `.dt` accessor.  Also any relevant cases in the sql code.

If we go down this route, I would follow this with analogous PRs for datetime.date, Decimal, ... 
Since the string version of this is in, this POC is no longer needed.  Closing.
