BLF: Perf: Add a kerning cache table for ascii chars.
This adds less than a megabyte of mem usage.
FT_Get_Kerning was the 2nd hotspot when profilling. This commit completly
remove this cost.
One concern though: I don't know if the kerning data is constant for every
sizes but it seems to be the case. I tested different fonts at different
dpi scalling and saw no differences.
