  Refactoring: move a few common functions to angle_test_util.
  
  Drop ScriptTest, Jamie says no longer needed.

  """Runs an isolated non-Telemetry ANGLE test.
  
  The main contract is that the caller passes the arguments:
  
    --isolated-script-test-output=[FILENAME]
  json is written to that file in the format:
  https://chromium.googlesource.com/chromium/src/+/main/docs/testing/json_test_results_format.md
  
  Optional argument:
  
    --isolated-script-test-filter=[TEST_NAMES]
  
  is a double-colon-separated ("::") list of test names, to run just that subset
  of tests. This list is parsed by this harness and sent down via the
  --gtest_filter argument.
  
  This script is intended to be the base command invoked by the isolate,
  followed by a subsequent non-python executable. For a similar script see
  run_performance_test.py.
