desktop-pwas: Adds ability to use the default launch container to PendingAppManager

WebAppPolicyManager allows admins to not specify a launch container.
When this is the case the installed app should launch in the default
container: windows for PWAs and tabs for non-PWAs.

Adds a new enum value to PendingAppManager::LaunchContainer to
indicate that the default launch container should be used and changes
WebAppPolicyManager to set that value when appropriate.
