URL: https://github.com/apache/hudi/pull/8760
### Change Logs
When there is only one file group for a given partition, we should avoid
clustering irrespective of whether sorting is enabled or not. Even if the data
within single file group may not be sorted, we don't really need to sort them,
since the stats are going to remain intact before and after sorting (total
valid values, min and max). So, even when sorting is enabled, we should not
trigger clustering when file group count is just 1.
### Impact
Will assist in avoid repeated clustering for partitions having 1 file group.
### Risk level (write none, low medium or high below)
low
