[trainer] Return Test Plan Configuration in JUnit output

Motivation and Context

We've started looking at using Test Plan configurations so that we can run our whole UI test suite against different dynamic font sizes. However, there is an issue when using fastlane + trainer to generate JUnit: There's no way to determine which Test Plan configuration the failure originated from - you just get duplicated <testsuite>s. We'd like to be able to raise the configuration that failed, and the information simply isn't there right now. For reference, this is how it appears within Xcode when you open the xcresult:

And how it appears in the JUnit file after this change:

Description

The Test Plan configuration name is already available to us (via ActionTestableSummary), it's just not being used anywhere yet. This PR makes a couple of changes:

• Retrieve the name from the ActionTestableSummary, and set it on the returned test results row as configuration_name.
• Looking at the JUnit spec, there's obviously nothing particularly specific to this case, so I settled on using a property on the testsuite, as defined in the spec called Configuration.

Testing Steps

The new field is now available on the xcresult based tests in test_parser_spec, so I have updated those, and I've added a new test within junit_generator_spec that verifies the output (also some extra coverage as currently there are no tests for xcresult -> junit).
