[I] Remove the deprecated bundled statistics providers [datafusion]
asolimando opened a new issue, #26055:
URL: https://github.com/apache/datafusion/issues/26055
### Is your feature request related to a problem or challenge?
#25969 deprecated the statistics providers bundled in `datafusion_physical_plan::operator_statistics`, since they duplicate or replace the estimation each operator does in `statistics_from_inputs`. The [API health policy deprecation guidelines] say deprecated APIs remain for
> 6 major versions or 6 months, whichever is longer
so they can be removed in `62.0.0` at the earliest (and no earlier than 6 months after the `56.0.0` release).
| Item | Deprecated in | Replacement |
| --- | --- | --- |
| `StatisticsRegistry::default_with_builtin_providers` | 56.0.0 | register user-defined providers, or none |
| `FilterStatisticsProvider` | 56.0.0 | `FilterExec` estimate (survival model tracked in #26052) |
| `JoinStatisticsProvider` | 56.0.0 | join operators' estimate (multi-key estimation tracked in #21583) |
| `ProjectionStatisticsProvider`, `PassthroughStatisticsProvider`, `AggregateStatisticsProvider`, `LimitStatisticsProvider`, `UnionStatisticsProvider` | 56.0.0 | operators' own estimate |
[API health policy deprecation guidelines]: https://datafusion.apache.org/contributor-guide/api-health.html#deprecation-guidelines
### Describe the solution you'd like
Remove the items above, their tests, and the helpers only they use (`computed_with_row_count`, `rescale_byte_size`).
### Describe alternatives you've considered
N/A
### Additional context
Follow-up to #25969 (closes #25571).
