enh: add select to InterchangeFrame

[MarcoGorelli]

We should allow for selecting columns by name in InterchangeFrame, falling back to select_columns_by_name for generic dataframe interchange protocol implementers

Started to take a quick look at this. For DuckDB and Ibis it should be doable with native methods.

For InterchangeFrame, since we both store _native_frame and _interchange_frame, the latter can be slices with select_columns_by_name, yet, how do we return the former object?

From a talk of yours I would conclude that it is by accessing .dataframe attribute, is this true generally? From the docs this is not very clear to me

[MarcoGorelli]

That was the "dataframe standard" 😄 The interchange protocol has no standardised way of getting the original dataframe object back

I think we can implement this for duckdb and ibis so it's at least available to plotly, and leave it not implemented for the more generic interchangeframe for now

I've opened an issue about this in the dataframe-api repo, but I'm not holding my breath regarding a response/decision: data-apis/dataframe-api#360
