Fix T71247: Outliner pose toggle looses bone selection

The outliner didn't account for weight-paint + pose-mode,
making it consider all pose bones unselected.
When syncing selection, bones were unselected.

This adds a context argument to passed to drawing functions since
finding the weight-paint pose-object in the drawing loop isn't efficient.
