[presto] Fixing the Writer count from the system config (prestodb#25941)

Summary:

In this diff I update the taskWriterCount and taskPartitionedWriterCount value to system config which was deleted in D80124169 diff.
kTaskWriterCount is important config for the Impulse connector created table to increase the parallism to ingestion the data by creating multiple writer drivers.
