Subject: [PATCH] Fix race condition in zone fill
When checking collisions, the SHAPE_POLY_SET::Collide() routine is not
const because it will regenerate the triangulation cache if it is out of
date (using a const_cast, grrr). This sidesteps the issue by assigning
a mutex to the triangulation caching
Fixes https://gitlab.com/kicad/code/kicad/-/issues/17180
