Dan Lambright 2509531123 Add test showing range tombstones can create excessively large compactions (#5956) 
Summary:
For more information on the original problem see this [link](https://github.com/facebook/rocksdb/issues/3977).

This change adds two new tests. They are identical other than one uses range tombstones and the other does not. Each test generates sub files at L2 which overlap with keys L3. The test that uses range tombstones generates a single file at L2. This single file will generate a very large range overlap that will in turn create excessively large compaction.

1: T001 - T005
2:  000 -  005

In contrast, the test that uses key ranges generates 3 files at L2. As a single file is compacted at a time, those 3 files will generate less work per compaction iteration.

1:  001 - 002
1:  003 - 004
1:  005
2:  000 - 005
