[hasanparasteh]

Summary

This PR fixes/implements the following bugs/features

• RTL text formating. It fixes RTL direction problem #2488 issue.

When I wanted to use jsPdf, html2pdf.js and etc, there was a problem with RTL text direction in rendering process. So this PR should add support to direction property for CanvasRenderingContext2D.direction and fix the problem.

I also created a reftests to demonstrate the problem and showing the issue is existing.

This PR parses the direction property from CSS but never applies it to the CanvasRenderingContext2D.direction property?

[hasanparasteh]

Yes. I just added direction property... now when you said it I realized that I forgot to apply it to CanvasRenderingContext2D.direction😅. I really wanted to fix the #2488 issue and this is what I came with to help me do the task I need. I think this PR needs more work to cover up the whole RTL problem
