Jonah Williams 1c923dd421 [Impeller] Fix 1d threadgroup dispatch size, Implement drawPoint geometry computation with compute, fallback to specialized CPU. (flutter/engine#42060) ...

Compute shader implementation of https://github.com/flutter/engine/pull/41803

I found this to be generally more straightforward, and we can revisit the vertex shader approach with GLES.

Benchmark is pending here: https://github.com/flutter/flutter/pull/126728

Note: rendering behavior is identical even though this is now a single draw call. This is becuase strokes have overdraw prevention enabled by default, while this new contents does not
