You can use the command key for \setupfloat to apply a macro to the
finished content of the float.
The purpose of this macro is to save the content and compare the width
to the width of the text are,
when the figure is wider then the available space use the \leftaligned
or \rightaligned commands
to let the content protrude to the outer margins.
\setuppagenumbering[alternative=doublesided]
\setuplayout[backspace=4cm,width=12cm]
\definemeasure[Widefigure][\textwidth+\rightmargindistance+\rightmarginwidth]
\setupfloat[figure][command=\FigureCommand]
\define\FigureCommand
 {\dowithnextbox
    {\signalrightpage
     \ifdim\nextboxwd>\textwidth
\doifrightpageelse{\leftaligned{\flushnextbox}}{\rightaligned{\flushnextbox}}%
     \else
       \midaligned{\flushnextbox}%
     \fi}
    \hbox}

With Wolfgang's solution, the captions remain centered on the page. With 
Hans's solution, the captions move with the center of the frame. I 
expect that, if captions are used and there are other figures that are 
not placed with this mechanism, Wolfgang's solution will result in a 
better looking page.
