MQE-768: Framework cannot depend on relative file structure to execute tests

[KevinBKozan]

Description

• MFTF and MFTF Tests can now interact with one another properly even if installed via composer. Pathing and anchoring is now done via composer autoload file checking.
• ModuleResolver now correctly refers to MAGENTO_BP instead of relative pathing.
