[FLINK-28861][table] Fix bug in UID format for future migrations and make it configurable

Before this commit, the UID format was not future-proof for migrations. The ExecNode version
should not be in the UID, otherwise, operator migration won't be possible once plan migration
is executed. See the FLIP-190 example that drops a version in the plan, once operator migration
has been performed. Given that the plan feature is marked as @Experimental, this change should
still be possible without providing backwards compatibility.

However, the config option table.exec.uid.format allows for restoring the old format and solves
other UID related issues on the way.

This closes #20555.
