sw: do not redline ContentControl items

When we redline the ContentControl item
itself, we break docx XML. Instead, we
only need to redline the placeholder,
which we already do.

This simply disables redlining when
inserting the ContentControl item
while leaving it otherwise enabled
while inserting the placeholder.

Before:

<w:body>
    <w:p>
        <w:pPr>
            <w:pStyle w:val="Normal"/>
            <w:rPr></w:rPr>
        </w:pPr>
==>     <w:ins w:id="-1" w:author="Unknown Author" w:date="2024-01-24T19:43:08Z">
        <w:sdt>
            <w:sdtPr>
                <w12:checkbox>
                    <w12:checked w14:val="0"/>
                    <w12:checkedState w14:val="2612"/>
                    <w12:uncheckedState w14:val="2610"/>
                </w12:checkbox>
            </w:sdtPr>
            <w:sdtContent>
                <w:r>
                    <w:rPr></w:rPr>
                </w:r>
==>         </w:ins>
==>         <w:ins w:id="0" w:author="Unknown Author" w:date="2024-01-24T19:43:08Z">
                <w:r>
                    <w:rPr></w:rPr>
                    <w:t>☐</w:t>
                </w:r>
==>         </w:ins>
                <w:r>
                    <w:rPr></w:rPr>
                </w:r>
            </w:sdtContent>
        </w:sdt>
    </w:p>
</w:body>

The first <w:ins> and its closing tag
is not seen in the reference docx
file, and we can see that it's invalid
XML here.

After:
<w:body>
    <w:p>
        <w:pPr>
            <w:pStyle w:val="Normal"/>
            <w:rPr></w:rPr>
        </w:pPr>
        <w:sdt>
            <w:sdtPr>
                <w12:checkbox>
                    <w12:checked w14:val="0"/>
                    <w12:checkedState w14:val="2612"/>
                    <w12:uncheckedState w14:val="2610"/>
                </w12:checkbox>
            </w:sdtPr>
            <w:sdtContent>
                <w:r>
                    <w:rPr></w:rPr>
                </w:r>
==>         <w:ins w:id="0" w:author="Unknown Author" w:date="2024-01-24T19:43:08Z">
                <w:r>
                    <w:rPr></w:rPr>
                    <w:t>☐</w:t>
                </w:r>
==>         </w:ins>
                <w:r>
                    <w:rPr></w:rPr>
                </w:r>
            </w:sdtContent>
        </w:sdt>
    </w:p>
</w:body>

Only the valid <w:ins> around the
placeholder exists.
