[PE] Don't early-out in LayoutSVGText::NodeAtFloatPoint

Since <text> can have descendants that may both differ in visibility as
well as fill/stroke, we can't evaluate pointer-events in LayoutSVGText,
but should rather let LayoutBlock (and SVGInlineTextBox et al) handle
the hit query. This makes LayoutSVGText somewhat similar to the same
method on LayoutSVGContainer.
