Currently, GPULock allows only one Spark task to acquire GPU resources at a time, which effectively makes GPU offloading run in single-threaded mode within a Spark executor. However, when testing the TPCDS queries, we observed that GPU utilization and memory usage can be very low (< 20%), meaning GPU resources are underutilized. To improve GPU utilization, this PR adds support for running multiple GPU tasks concurrently through the configuration `spark.gluten.sql.columnar.backend.velox.cudf.concurrentGpuTasks`.
