Enabled internal test code at the suite-level
Test suites already had the ability to provide suite-level code via the "code" attribute, but this was placed in the suite's generated source file, making it inaccessbile to internal tests. This change allows suite code to be placed in the same place as internal tests, via the "in" attribute, though this has some caveats: 1. Suite-level code generally declares helper functions in global scope. We don't parse this code or anything, so name collisions between helper functions across different test suites is up to the developer to resolve. 2. Internal suite-level code has access to internal functions/variables/ etc, this means we can't place a copy in our suite's generate source and expect it to compile. For this reason, internal suite-level code is unavailable for non-internal tests in the suite. This also means you only get to place internal suite-level code in a single source file. Though this is not really an issue since littlefs is basically a single file...
