The extensive use of notes in overview documentation should be avoided.
All the notes are concerned with performance considerations, so
let's group them together in one section.

The original attempt, deb238586a "QQuickIcon: Resolve URL relative to
current element," works fine for IconLabel itself, but not for Buttons
containing IconLabel.

  // <style>/Button.qml
  T.Button {
      id: control
      icon:  // owner: control
      contentItem: IconLabel {
          icon: control.icon  // owner: this, but should be control
      }
  }

  // user code
  Button { icon.source: "a.png" }

Since IconLabel is an implementation detail of the Button, IconLabel.icon
owner needs to point to the Button so the user-specified icon.source can
be resolved relative to the user code, not to the <style>/ directory.

This patch fixes the problem by explicitly resolving the source URL on
setIcon() and propagating the resolved icon object to the inner items.
If the relative URL has already been resolved by e.g. Button, the inner
IconLabel never resolves the URL again to itself.

The problem could be addressed by initializing icon owner only once by
Action/Button constructor, but that would lead to dangling owner pointer
as icon object could be copied anywhere. So I've added resolvedSource
data member in place of the owner pointer.

  Button { id: dangling }
  Button { id: victim; icon: dangling.icon }  // owner: dangling
  Component.onCompleted: dangling.destroy()
  // ... would SEGV (or use after free) if victim.icon.source modified.
