[Enhancement] Optimize MaterializedView's inferDistribution policy by using existing tablets (backport #63367)

[mergify]

Why I'm doing:

#26726 may create mv with many buckets(200/500) if there are many compute nodes(eg: 30) which will cause the culster unstable because of huge metadata in FE.

The current implementation hasn't taken hash/random distribution yet and may generate too many tablets:

public void inferDistribution(DistributionInfo info) throws DdlException {
    if (info.getBucketNum() == 0) {
        int inferredBucketNum = 0;
        for (BaseTableInfo base : getBaseTableInfos()) {
            Optional<Table> optTable = MvUtils.getTable(base);
            if (optTable.isEmpty()) {
                continue;
            }
            Table table = optTable.get();
            if (table.isNativeTableOrMaterializedView()) {
                OlapTable olapTable = (OlapTable) table;
                DistributionInfo dist = olapTable.getDefaultDistributionInfo();
                inferredBucketNum = Math.max(inferredBucketNum, dist.getBucketNum());
            }
        }
        if (inferredBucketNum == 0) {
            inferredBucketNum = CatalogUtils.calBucketNumAccordingToBackends();
        }
        info.setBucketNum(inferredBucketNum);
    }
}

What I'm doing:

Use OlapTable's implementation (#38763) to deduce mv's default bucket by default.
