libpayload: cbgfx: Add color mapping functionality
Similar to set_blend(), add set_color_map() for mapping background and
foreground colors of a bitmap. Also add clear_color_map() for clearing
the saved color mappings.
Note that when drawing a bitmap, the color mapping will be applied
before blending.
Also remove unnecessary initialization for static variable 'blend'.
