Auto merge of #24573 - teapotd:is-point-in-path-nan, r=jdm

Return false from CanvasState::is_point_in_path for NaN/infinite values

Servo doesn't pass WPT test `/2dcontext/path-objects/2d.path.isPointInPath.nonfinite.html` when built with raqote (see [here](https://github.com/servo/servo/pull/24470#issuecomment-546009000)).
This change adds a missing check for NaN/infinite values in `CanvasState::is_point_in_path` and fixes this.
