Allow the DeckSpinnerSelection to be used in Stats Fragment

[criticalAY]

The deck spinner requires collection load function override for col and AnkiActivity as parameter.
We only need the deck names for the stats fragment to allow the hack to allow the user to change the deck from the stats fragments itself so we need refactoring in DeckSpinnerSelection

• I have read the support page and am reporting a bug or enhancement request specific to AnkiDroid
• I have checked the manual and the FAQ and could not find a solution to my issue
• I have searched for similar existing issues here and on the user forum
• (Optional) I have confirmed the issue is not resolved in the latest alpha release (instructions)
