Campbell Barton 397731d4df BLI_math: improve symmetrical values from sin_cos_from_fraction 
When plotting equally distant points around a circle support an extra
axis of symmetry so twice as many exact values are repeated than
originally added in [0], see code-comments for a detailed explanation.
Tests to ensure accuracy and exact symmetry have been added too.

Follow up on fix for T87779.
