Compute grapheme list for mid-ligature support on demand

This patch changes to compute grapheme list for mid-ligature
support only when needed.

This patch is part of the LayoutNG performance efforts.
As we measure LayoutNG performance, computing grapheme list
for every ShapeResult turned out to be not cheap.
