Closely related to #3219, but focused on GeoParquet.

GeoParquet 1.1 added a bunch of encodings: https://github.com/opengeospatial/geoparquet/blob/main/format-specs/geoparquet.md#native-encodings-based-on-geoarrow

We should ensure we can both read and write files with such encoding for the geometry column(s).

For writing, we can have an encoding keyword which still defaults to "WKB", but where can specify one of the new encodings as well ("point", "linestring" etc).
We could maybe also accept an additional value of "geoarrow" that will then infer the actual geometry-specific encoding from the data?
