LibWeb: Improve support for SVG text positioning attributes

Previously, we only supported very basic numbers and a single level of
text positioning support in the `x`, `y`, `dx` and `dy` attributes in
`<text>` and `<tspan>` SVG elements.

This improves our support for them in the following ways:

  * Any `length-percentage` or `number` type value is accepted;
  * Nested `<text>` and `<tspan>` use the 'current text position'
    concept to determine where the next text run should go;
  * We expose the attributes' values through the API.

Though we still do not support:

  * Applying the `rotate` attribute;
  * Applying transformations on a per-character basis.
  * Proper horizontal and vertical glyph advancing (we just use the path
    bounding box for now).
