Test: only report details on failure

[mratsim]

The test_suite is verbose and reports the full details of the tests.

With over 70 active tests and 40 benchmarks, the output is unreadable.

Instead we should report details only on failure otherwise:

• if test is in progress
  spinning icon/emoji, test name, time started
• if test is finished
  green checkmark or [OK], test name, time started, time taken

This concise output can be done for nimble test_parallel only leaving nimble test as-is.
Modification likely has to be done in pararun, by not flushing output in sync to stdout but keeping it in a buffer
