altos/stm-vga: Implement VGA out from the STM processor
Generates vsync/hsync using timers and pixel data using the SPI port.
320x240 video using 640x480 mode and a 24MHz "pixel" clock.
Includes the beginings of rendering code for the frame buffer,
including bitblt, solid fill and text with a 5x7 font.
