canvas: Add CanvasTransform 'setTransform(transform)' method (#37692)

Follow the HTML canvas specification and add missing
'setTransform(transform)' method to CanvasTransform interface.

https://html.spec.whatwg.org/multipage/#dom-context-2d-settransform-matrix

The third-party WebIDL doesn't support different extended attributes
on different overloads of methods, so 'Throws' attribute was added
to another 'setTransform(...)' method.

Testing: Improvements in the tests
- css/geometry/DOMMatrix*
-
html/canvas/element/transformations/2d.transformation.setTransform.multiple.html
-
html/canvas/offscreen/transformations/2d.transformation.setTransform.multiple

New failing tests due to disabled 'paint worklet' feature
- css/css-paint-api/setTransform-00*.https.html
