uterm: video: add blend() helper

When drawing single glyphs we often have the glyph as alpha-only buffer so
we can draw it with any color we want. blit() requires a full image that
can be copied, so the new blend() helper is introduced which takes a
foreground and background color and blends in an image. Only plain-alpha
buffers are currently supported.
