…35856) My test show that get_delete_bitmap from metaservice may cost too much time while doing sync_rowset in cloud mode, which may lead to calculating delete bitmap slow on publish phase, we can use the existing delete bitmap cache to slove this problem.

…map from cache failed (#41309) ## Proposed changes Issue Number: close #xxx To accelerate the speed of sync latest delete bitmap, #35856 try to get the delete bitmap from `CloudTxnDeleteBitmapCache` first. In the following situation, compaction may get empty delete bitmap and cause duplicate key: 1. compaction started 2. several load succeed during the compaction 3. compaction finished data merging and start to calculate delete bitmap generated by latest load tasks 4. compaction try to sync rowset and delete bitmap, it get delete bitmap first from `CloudTxnDeleteBitmapCache` 5. `CloudTxnDeleteBitmapCache::get_delete_bitmap()` can get txn infos from it's inner map, but cache missed when it try to get delete bitmap from LRU cache, it don't report error but returned an empty delete bitmap 6. compaction used wrong delete bitmap, duplicate key occured.
