### What changes were proposed in this pull request? 1. Check that the partition identifier passed to `SupportsPartitionManagement.partitionExists()` is fully specified (specifies all values of partition fields). 2. Remove the custom implementation of `partitionExists()` from `InMemoryPartitionTable`, and re-use the default implementation from `SupportsPartitionManagement`. ### Why are the changes needed? The method is supposed to check existence of one partition but currently it can return `true` for partially specified partition. This can lead to incorrect commands behavior, for instance the commands could modify or place data in the middle of partition path. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? By running existing test suites: ``` $ build/sbt "test:testOnly *AlterTablePartitionV2SQLSuite" $ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *SupportsPartitionManagementSuite" ``` Closes #30667 from MaxGekk/check-len-partitionExists.
