1. Minimal reproduce step (Required)

we get the "suqash delete range" to estimate whether there are sufficient delete rows that we need to compact data in background thread.

In ColumnFileSetSnapshot::getSquashDeleteRange, it use the member variable is_common_handle, rowkey_column_size to generate the rowkey range.
But actually those two variable are not set correctly. is_common_handle is always false in ColumnFileSetSnapshot

So when the table use common-handle, shouldCompactDeltaWithStable always returns false, and the segment background gc is not GC in timely
