Integration test - parameterized mobile property ID

[timkimadobe]

[!NOTE] This change is intended to match the Android PR: https://github.com/adobe/aepsdk-edge-android/pull/163

Description

This PR updates the integration tests to accept a parametrized mobile property ID instead of the old environment switcher. It involves:

1. Changes to the entire testing pipeline to apply these changes: GitHub workflow -> Makefile -> Integration test
2. Replacing custom enums for location hint and edge environment with a more streamlined test constants + test environment helper

Questions for reviewers

1. Should the modified TestEnvironment struct be merged with the extension TestBase in TestBase+EdgeHelpers.swift? Or does it make more sense to keep these separate?
2. Do we like having a dropdown picker for location hint in the workflow or should it be an open String input?
   • The downstream implication of the current picker is that any other option would require a code change
   • Using an open String input would also allow removing the special case handling enum LocationHintMapping
