go.*,text: update go-text to pick up font transformation caching

Browse Source 
This commit picks up improvements in upstream go-text that (among other things)
allow the shaper to reuse a lot of information when shaping the same font face
multiple times (using an LRU cache to keep that information available). I've
tried to pick a reasonable default LRU size of 32 faces.

My simple benchmarks indicate a definitive performance gain and reduction in
memory use across the board, which is especially noticable for complex fonts
like arabic and emoji.
