[BUG] checkValue does not work in RapidsConf

[sinkinben]

Describe the bug
In RapidsConf.scala, there are some ConfigBuiler object. For example,

  val MULTITHREAD_READ_NUM_THREADS = conf("spark.rapids.sql.multiThreadedRead.numThreads")
      .doc("The maximum number of threads on each executor to use for reading small " +
        "files in parallel. This can not be changed at runtime after the executor has " +
        ...
        ".")
      .integerConf
      .checkValue(v => v > 0, "The thread count must be greater than zero.")
      .createWithDefault(0)

Here checkValue does not work. createWithDefault(-1) or createWithDefault(0) will not throw any exception.

Even if "spark.rapids.sql.multiThreadedRead.numThreads" = -1 is set explicitly by user, there is no exception, either.

Steps/Code to reproduce bug
Run spark-rapids locally via:

spark-shell --jars ${RAPIDS_JAR} \
  --conf spark.sql.adaptive.enabled=false \
  --conf spark.plugins=com.nvidia.spark.SQLPlugin \
  --conf spark.rapids.sql.multiThreadedRead.numThreads=-1
 
scala> val key = "spark.rapids.sql.multiThreadedRead.numThreads"                                                                    
key: String = spark.rapids.sql.multiThreadedRead.numThreads                                                                         
                                                                                                                                    
scala> spark.conf.get(key)

scala> :quit

Expected behavior
When spark.rapids.sql.multiThreadedRead.numThreads <= 0, we should throw an IllegalArgument exception.

In original spark, if we set an invalid parameter, there is an IllegalArgument.

$ spark-shell --conf spark.sql.shuffle.partitions=-1
