* [jvm-packages] fix spark-rapids compatibility issue
spark-rapids (from 22.10) has shimmed GpuColumnVector, which means
we can't call it directly. So this PR call the UnshimmedGpuColumnVector
* [jvm-packages] fix executor crashing issue when transforming on xgboost4j-spark-gpu
the API XGBoosterSetParam is not thread-safe. Dring the phase of transforming,
XGBoost runs several transforming tasks at a time, and each of them will set
the "gpu_id" and "predictor" parameters, so if several tasks (multi-threads)
all XGBoosterSetParam simultaneously, it may cause the memory to be corrupted
and cause SIGSEGV.
This PR first get the booster from broadcast and set to the correct gpu_id
and predictor, and then all transforming taskes will use the same booster to
do the transforming.
xgboost4j-spark provides 2 sets of API for setting features, one for CPU, another for GPU, which may cause confusion.
This PR removes the GPU API and adds an override CPU function setFeaturesCol to accept Array[String] parameters.
* [CI] Clean up build for JVM packages
* Use correct path for saving native lib
* Fix groupId of maven-surefire-plugin
