[Edge] Allow SSO with primary account by default

The WebView feature to allow SSO has been made accessible but disabled
by default. With this change, the feature is enabled by default, still
allowing to opt-out via system property. This aligns with the previous
behavior of the IE engine.

Fixes #2658
