Compact requires a forced checkpoint of the file(s) being compacted. Currently there are 3 forced checkpoints. WT-9628 will change this to only force the last checkpoint.

All that compact needs is a forced checkpoint of the file(s) it is compacting. This needs to happen as part of a system-wide checkpoint for correctness (see WT-2969), but there is no need to force-checkpoint the files that compact isn't working on. 

Adding a checkpoint option to perform a system-wide checkpoint with a list of files that should be force-checkpointed would provide the required correctness more efficiently.
