Review Comment:
   Validates that the provided `partitionSpec` is a valid according to the 
current or past table partitioning.
   The existing method `validatePartSpec` validates that the spec is valid 
based on current table partitioning only. This isn't enough for Iceberg 
compaction on partition level with evolution because the partition spec 
provided in compaction command may correspond for an old partitioning.
