[SPARK-53104][PS] Introduce ansi_mode_context to avoid multiple config checks per API call

What changes were proposed in this pull request?

Introduces ansi_mode_context to avoid multiple config checks per API call.

Why are the changes needed?

Currently is_ansi_mode_enabled is called many times, which could cause a performance issue as it retrieves the related config every time it's called.

For example:

many_columns = ps.DataFrame({f"col_{i}": [i] for i in range(500)})
many_columns + 1

will cause the roundtrip between the client and the server 500 times. To be exact, classic needs two roundtrips to check configs, so the number is 1000 times.

We should reduce the number of retrievals to at most once (or twice in classic) per API call.

Does this PR introduce any user-facing change?

No.

How was this patch tested?

The existing tests should pass, also manually checked the number of config retrivals.

Was this patch authored or co-authored using generative AI tooling?

No.

The PR looks good. I think docstring on how to use is_ansi_mode_enabled and ansi_mode_context would be helpful. I can follow up with that.
