Vadim Zeitlin c0dbe808a6 Move SetBitmap() and GetBitmap() to wxMenuItemBase
Ensure that all derived classes have these functions and let them to
avoid defining them if they can just use the default implementation,
which was the case for most ports.

Also move m_bitmap to the base class from the derived ones.

No real changes.
