video: Update truetype console to support copy buffer

Browse source 
Update the implementation to keep a track of what it changes in the frame
buffer and then tell the copy buffer about it. Use the special
vidconsole_memmove() helper so that memmove() operations are also
reflected in the copy buffer.
