DolphinWX: Separate the information panel from ISOProperties

Makes the information panel self-contained.

This was done first, as opposed to isolating the GameConfig panel--the
first panel in the group--as this panel had code all over the place in
ISOProperties, so I figured it'd be best to fix this one up first.
