Uptake requireTestIsolation to replace TestGroups.json (#4165)

#### Summary <!-- Provide a general summary of your changes -->

~Replace `System Application Tests (No Isolation)` project with the
latest `RequireTestIsolation` property.~ Couldn't figure out how to run
`Run-TestsInBcContainer` twice, it is failing build...

Replace `TestGroups.json` with the latest `RequireTestIsolation`
property. This is a follow up for #4137 .

The change simplifies the build script, removing the need to maintain
the `TestGroups.json`.
