Track a ttfd span per Activity

[stefanosiano]

📜 Description

Added map of ttfd spans in ActivityLifecycleIntegration, to automatically stop only the correct one.

💡 Motivation and Context

Due to Activity lifecycle, during a navigation between two activities, when the previous activity was destroyed the ActivityLifecycleIntegration was terminating the ttfd span of the new activity.

💚 How did you test it?
