config: tweak.surface-bit-depth: add support for 16-bit surfaces

Browse source 
This adds supports for 16-bit surfaces, using the new
PIXMAN_a16b16g16r16 buffer format. This maps to
WL_SHM_FORMAT_ABGR16161616 (little-endian).

Use the new 16-bit surfaces by default, when
gamma-correct-blending=yes.
