Code Review
This pull request introduces a GetOptionalStroke method to the Paint struct to centralize stroke parameter retrieval, replacing manual style checks in canvas.cc and dl_dispatcher.cc. Unit tests were added to verify the new functionality. Feedback suggests simplifying the GetOptionalStroke implementation using a ternary operator to improve readability and ensure all code paths return a value.

There are a few places where a set of stroke parameters are provided as an
std::optional<StrokeParameters>object, but the construction of that optional value requires conditional evaluation of the properties of the Paint object. This PR adds a new getter on Paint that optional provides the StrokeParameters only if the paint is a stroking paint.Pre-launch Checklist
