Jonah Williams 41346b0801 [Impeller] Reland: remove most temporary allocation during polyline generation. (flutter/engine#52180) ...

Part of https://github.com/flutter/flutter/issues/143077

Only allocate into reused arenas instead of allocating a new vector of data. Fixes https://github.com/flutter/flutter/issues/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.

Fixes missing points in case a filled path is not explicitly closed.
