Yu-Ping Wu b086728094 libpayload: cbgfx: Add draw_line() 
Add a function draw_line() to draw either a horizontal or vertical line
segment.

Theoretically a horizontal line can also be drawn by calling
draw_rounded_box() with dim_rel.x being the line length and dim_rel.y
being the line width. However, due to the truncation in integer division
when converting relative coordinates to absolute ones, this will
potentially produce inconsistent line widths, depending on the value of
pos_rel.y.

It is guaranteed that draw_line() will produce consistent line widths,
regardless of the position of the line. Also, when the thickness
argument is zero, this function is able to draw a line with 1-pixel
width, which is not achievable by draw_rounded_box().
