[backport] jvm-packages 1.6.1 (#7849)
* [jvm-packages] move the dmatrix building into rabit context (#7823)

This fixes the QuantileDeviceDMatrix in distributed environment.

* [doc] update the jvm tutorial to 1.6.1 [skip ci] (#7834)

* [Breaking][jvm-packages] Use barrier execution mode (#7836)

With the introduction of the barrier execution mode. we don't need to kill SparkContext when some xgboost tasks failed. Instead, Spark will handle the errors for us. So in this PR, `killSparkContextOnWorkerFailure` parameter is deleted.

* [doc] remove the doc about killing SparkContext [skip ci] (#7840)

* [jvm-package] remove the coalesce in barrier mode (#7846)

* [jvm-packages] Fix model compatibility (#7845)

* Ignore all Java exceptions when looking for Linux musl support (#7844)
