In rare situations if a light is placed near colinear to a frustum edge, the extra culling plane derived can have an inaccurate normal due to floating point error.
This PR detects colinear triangles, and prevents adding a culling plane in this situation.
Using 2.2.7.dev115+g0eb441d6.
Had to add `cancelled` to the ignore list, as it's a Wayland signal which
we're handling in our code, so we don't want codespell to fix that "typo".
Also includes the typo fix from #87927.

Existing shadow caster culling takes no account of the camera.
This PR adds the highly encapsulated class RenderingLightCuller which can cut down the casters in the shadow volume to only those which can cast shadows on the camera frustum.
