HPCC-10271 Simplify selection between CCsvPartitoner and CCsvQuickPartioner.

Add code to check the source file is quoted or not at the partitioner creation
stage. If it is quoted then use CCsvPartitioner() else use
CCsvQuickPartitioner.

Remove unnecessary code from CCsvQuickPartitioner constructor and
CCsvPartitioner::findSplitPoint() method.
