docs: formatdomain: Document the CPU feature 'name' attribute

Currently, the CPU feature 'name' XML attribute, as in:

    [...]
    <cpu match='exact'>
      <model fallback='forbid'>IvyBridge</model>
      <vendor>Intel</vendor>
      <feature policy='require' name='pcid'/>
    </cpu>
    [...]

isn't explicitly documented in formatdomain.html.

Document it now.
