This change reverts the following previous change:
Part of flutter/flutter#143077
Only allocate into reused arenas instead of allocating a new vector of data. Fixes flutter/flutter#133348
Also moves tessellation logic into the c/tessellator and out of the impeller tessellator. This was necessary to fix a compilation error. introduced by including host_buffer -> allocator -> fml mapping -> window.h include which has a function definition that conflicts with the c tessellator definition.
