Perspective transformations are non-affine, whereas the transformation
capabilities in SVG allow for only affine transformations. That's why
you can't find any SVG-esque way to do what you want. (In particular,
transforming a rectangle into a trapezoid is a non-affine
transformation, because it takes lines that were originally parallel and
makes them not parallel.)
