[FEA] Move kudo code from jni repo to plugin repo

[binmahone]

Is your feature request related to a problem? Please describe.

Currently most of the Kudo code reside in spark-rapids-jni, this makes it hard to integrate Kudo with the existing SpillFramework. For example, instead of having a member "HostMemoryBuffer buffer", we can replace it with "SpillableHostBuffer buffer" (SpillableHostBuffer is a concept in plugin) to make KudoTable responsive to host memory shortage.

It can break down into 2 subtasks:

1. first PR in spark-rapids to create a new folder in spark-rapids, i.e. sql-plugin/src/main/java/com/nvidia/spark/rapids/kudo and copy every kudo class from jni into this Move kudo related classes to plugin #12172
2. second PR in spark-rapids-jni to safely delete kudo classes delete all kudo related classes and tests from spark-rapids-jni spark-rapids-jni#2960

@revans2 @liurenjie1024 comments from your side will be appreciated

Last time I had a talk with @GaryShen2008 to discuss whether we need to use cpp to implement kudo on cpu as it's a compute intensive part, but currently it's not determined yet since we need to collect data to prove its roi. Without that, I'm +1 moving it to plugin side.

Bobby suggest not to move out of JNI repo
