Fixes#11089 - cleanup PATH on MSI uninstall
Additionally fixes scenarios where the path can be overwritten by setx
Also removes the console flash, since the helper is built as a silent gui
Helper executable can be rerun by user to repair PATHs broken by other tools
Utilizes executable location instead of passed parameters to remove delicate escaping requirements
[NO NEW TESTS NEEDED]
