Xinrong Meng 04a8d2cbcf [SPARK-35343][PYTHON] Make the conversion from/to pandas data-type-based for non-ExtensionDtypes 
### What changes were proposed in this pull request?

Make the conversion from/to pandas (for non-ExtensionDtype) data-type-based.
NOTE: Ops class per ExtensionDtype and its data-type-based from/to pandas will be implemented in a separate PR as https://issues.apache.org/jira/browse/SPARK-35614.

### Why are the changes needed?

The conversion from/to pandas includes logic for checking data types and behaving accordingly.
That makes code hard to change or maintain.
Since we have introduced the Ops class per non-ExtensionDtype data type, we ought to make the conversion from/to pandas data-type-based for non-ExtensionDtypes.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Unit tests.

Closes #32592 from xinrong-databricks/datatypeop_pd_conversion.
