Jonah Williams 7f0892aaeb [Impeller] disable overdraw prevention for source draws. (flutter/engine#56403) 
Overdraw prevention prevents overlapping triangles in the stroke tessellator from being visible with partially opaque draws. For fully opaque draws (or usage of src blend mode) I do not believe this will be an issue - so we can disable this to speed things up a tiny bit.

This code runs after we covert opaque draws to src blend mode, so checking for src blend mode should be sufficient.
