Mention InvalidateBestSize() in DoGetBestClientSize() documentation.

It is not obvious that it needs to be called when the best size changes, so
give at least a hint.

         GetBestSize() returns an arbitrary hardcoded size for the window, so
         you must override it when implementing a custom window class.
 
+        Notice that the best size returned by this function is cached
+        internally, so if anything that results in the best size changing (e.g.
+        change to the control contents) happens, you need to call
+        InvalidateBestSize() to notify wxWidgets about it.
