Run relevant tests

[NoaheCampbell]

Description, Motivation and Context

Instead of running every test for all changes, this aims to run only tests that are relevant to the changes made in a pull request. For example if a PR introduces changes to collectors, it would run preflight and support bundle tests since both are affected, however if a change is only made to preflight, only preflight tests would be run.

The reason behind this is to reduce time spent on waiting for tests to run and pass or fail as there are many situations where not every single test needs to be run
