IMPALA-14569: Fix IllegalStateException in partition pruning on type mismatch

This fixes an IllegalStateException in HdfsPartitionPruner when
evaluating 'IN' predicates whose consist of two compatible types, for
example DATE and STRING: date_col in (<date as string>).

Previously, 'canEvalUsingPartitionMd' did not check if the slot type
matched the literal type. This caused the frontend to attempt invalid
comparisons via 'LiteralExpr.compareTo', leading to
IllegalStateException or incorrect pruning.

The fix ensures 'canEvalUsingPartitionMd' returns false on type
mismatches, deferring evaluation to the backend where proper casting
occurs.

Testing:
- Added regression test in hdfs-partition-pruning.test.
