jgruber ea48d0942a [debugger] Further stepping support in test wrapper
This CL adds further support to the test wrapper. We are now able to
run almost all mjsunit/debug-step-* tests using the inspector backend.

debug-stepframe-* tests are not yet supported since inspector does not
know a 'frame' step type.

The interface has also been improved to be able to move these tests to
inspector mostly without modification.
