`DataScan` `count` method does not respect limit

### Apache Iceberg version

0.9.1 (latest release)

### Please describe the bug 🐞

When calling `count()` on a `DataScan`, limit is not respected. Seems trivial but if I set a limit of 5 I expect 5 or less rows back, at least with a scan-like implementation

The underlying `ArrowScan` does not get passed the limit param

https://github.com/apache/iceberg-python/blob/main/pyiceberg/table/__init__.py#L1940

This results in scans taking longer due to not respecting the limit.

The fix will involve more than just passing the limit to the `ArrowScan`

Start in pyiceberg/table/__init__.py around line 1940 and trace DataScan.count through the underlying ArrowScan call. Check how the limit is propagated and identify the additional scan behavior the issue notes may need adjustment. Done means count() returns no more than the requested limit while avoiding unnecessary scan work.
