📜 Description

Make an empty DataCollection neutral and add forceDataCollection() as the explicit way to opt into the documented Data Collection defaults without configuring an individual option.

Remove the internal boolean constructor and update SDK-owned configuration objects to use the neutral no-argument constructor. Keep SentryOptions.setDataCollection(...), but document that replacing the object discards options already configured on that instance.

💡 Motivation and Context

Constructing and assigning an empty DataCollection previously activated the new defaults while replacing values already loaded from external configuration or Android manifest metadata. Calling options.getDataCollection().forceDataCollection() now activates those defaults on the existing object, preserving configuration from other sources.
