Jonah Williams e673b6fb32 [Impeller] generate stroke vertices into point arena. (flutter/engine#56390) 
Heap allocation is extremely expensive on Android.

We can speed up the stroke tessellation by allocation a large arena and using that to write vertices. If the vertices would overflow, we switch to a dynamically allocated vector.
