Add more resiliency when communicating with DTE

Since this is a cross-process operation that may involve attempting to acquire the UI thread while the target VS is actually busy, it may actually fail with a COM exception. In that case, default to not throwing, since that destabilizes the MSBuild process and causes us to not recover the active tracking once the UI thread lock is gone.

Check version for IDE builds only

Ensure VS version only in the IDE builds, since for CLI builds, as long as there is either a `$(StartupFile)` or an `$(ActiveDebugProfile)` that matches a file in the project, things will still work just fine, although there will be no launchSettings.json generation.

Only write launchsettings if changed

This avoids unnecessary refreshes in the compiler.
