[SPARK-36774][CORE][TESTS] Move SparkSubmitTestUtils to core module and use it in SparkSubmitSuite

### What changes were proposed in this pull request?

This PR refactors test code in order to improve the debugability of `SparkSubmitSuite`.

The `sql/hive` module contains a `SparkSubmitTestUtils` helper class which launches `spark-submit` and captures its output in order to display better error messages when tests fail. This helper is currently used by `HiveSparkSubmitSuite` and `HiveExternalCatalogVersionsSuite`, but isn't used by `SparkSubmitSuite`.

In this PR, I moved `SparkSubmitTestUtils` and `ProcessTestUtils` into the `core` module and updated `SparkSubmitSuite`, `BufferHolderSparkSubmitSuite`, and `WholestageCodegenSparkSubmitSuite` to use the relocated helper classes. This required me to change `SparkSubmitTestUtils` to make its timeouts configurable and to generalize its method for locating the `spark-submit` binary.

### Why are the changes needed?

Previously, `SparkSubmitSuite` tests would fail with messages like:

```
[info] - launch simple application with spark-submit *** FAILED *** (1 second, 832 milliseconds)
[info]   Process returned with exit code 101. See the log4j logs for more detail. (SparkSubmitSuite.scala:1551)
[info]   org.scalatest.exceptions.TestFailedException:
[info]   at org.scalatest.Assertions.newAssertionFailedException(Assertions.scala:472)
```

which require the Spark developer to hunt in log4j logs in order to view the logs from the failed `spark-submit` command.

After this change, those tests will fail with detailed error messages that include the text of failed command plus timestamped logs captured from the failed proces:

```
[info] - launch simple application with spark-submit *** FAILED *** (2 seconds, 800 milliseconds)
[info]   spark-submit returned with exit code 101.
[info]   Command line: '/Users/joshrosen/oss-spark/bin/spark-submit' '--class' 'invalidClassName' '--name' 'testApp' '--master' 'local' '--conf' 'spark.ui.enabled=false' '--conf' 'spark.master.rest.enabled=false' 'file:/Users/joshrosen/oss-spark/target/tmp/spark-0a8a0c93-3aaf-435d-9cf3-b97abd318d91/testJar-1631768004882.jar'

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

I manually ran the affected test suites.

Closes #34013 from JoshRosen/SPARK-36774-move-SparkSubmitTestUtils-to-core.
