[iceberg] Reduce redundant getTable calls in IcebergHiveMetadata

[imjalpreet]

Description

After #24326, redundant metastore calls can lead to significant performance degradation.

This PR introduces a per-query caching mechanism for Hive table objects in the IcebergHiveMetadata class to improve performance by reducing repeated calls to the metastore.

The chart below compares TPCH queries executed in my local environment. It illustrates execution times before disabling the metastore cache, the current master, and after the optimization introduced in this PR.
