Add a simple implementation of CanvasRenderingContext2d.fillText

<!-- Please describe your changes on the following line: -->
I added a simple implementation of CanvasRenderingContext2d.fillText.
Some code are merged from @mikrut, and I fixed a bug about text scaling.
Also, the bug of text rotation should be fixed after `raqote` merged my other PR.
