Support withheld to filter out elements defined in the schema filters configurations in Lucene query output

[josegar74]

Similar to #6869, but for 3.12.x to support withheld filter elements in Lucene query output.

Also includes:

• Add support for authenticated operation in metadata operation filters.
• Fix in the metadata operation filters XPATH expressions in iso19139 and iso19115-3.2008 schemas.
• Fix in MEF export formats to withheld elements.

A test case:

1. Edit https://github.com/geonetwork/core-geonetwork/blob/3.12.x/schemas/iso19115-3.2018/src/main/plugin/iso19115-3.2018/update-fixed-info.xsl and add the following template to withheld all contacts, except the Identification Info > Point of Contact (Contact for the resource).

  <!-- Withheld mdb:contact, cit:citedResponsibleParty, mrd:distributorContact elements -->
  <xsl:template match="mdb:contact|cit:citedResponsibleParty|mrd:distributorContact" priority="10">
    <xsl:copy>
      <xsl:copy-of select="@*[name() != 'gco:nilReason']" />
      <xsl:attribute name="gco:nilReason">withheld</xsl:attribute>

      <xsl:apply-templates select="*" />
    </xsl:copy>
  </xsl:template>

2. Create an ISO19115-3.2008 metadata with the template for geographical data.

3. Check the metadata default view, full view, pdf: all contacts should be displayed. The XML view should contain all the contact details.

4. Publish the metadata.

5. With an anonymous user or a logged user that can't edit the metadata, check the metadata default view, full view, pdf: only the Identification Info > Point of Contact (Contact for the resource) should be displayed. The XML view should contain the contact details for Identification Info > Point of Contact (Contact for the resource), for the others should contain the root element with the attribute gco:nilReason=""withheld" without containing the contact information.
