Use real InputWindowInfo for traces and dumps

Right now we use the InputWindowInfo stored in the drawingState.
However, that doesn't include all the data sent to InputDispatcher since
we fill a lot of the data in when calling fillInputInfo. Instead, call
fillInputInfo when ready to add proto data so the InputWindowInfo shows
what's actually being used.

Test: winscope shows correct information
