graphics/nxglib: use putarea for lcd copyrectangle when available
For LCD drivers that implement putarea(), use it to copy the entire
rectangle in a single call instead of per-row putrun() calls. This
avoids the per-row overhead of setting the display window
(CASET+RASET over SPI) for every scanline.
