wasp: draw565: Optimize the 2-bit RLE drawing functions
...
There's a bunch of different changes here but there are only really three
big wins. The biggest win comes from restructuring the 2-bit RLE decode
loop to avoid the inner function (~20%) but the switch to 16-bit writes in
_fill() and adoption of quick_write (e.g. no CS toggling) are also
note worthy (and about 5% each).

This makes line-by-line drawing more efficient because don't have to
handle the dc line. The optimization targets font rendering and if good
for slightly less than 10% rendering improvement.

drivers: st7789: Optimize RLE decoding loop
...
Migrate the filling of the line buffer into a seperate function.
This does naturally reduce the cost of the loop management but
much more importantly allows us to use viper native code
generator.

Currently this just traces SPI activity from the ST7789 driver but its
a good baseline to start building up test functions from.
