Backport Make the bootstrap order of cms-dashboard, cms-reports, cms-browser and cms-admin deterministic

Currently it is

<!-- CMS dashboard perspective -->
<sv:node sv:name="cms-dashboard">
<sv:property sv:name="jcr:primaryType" sv:type="Name">
<sv:value>hippo:initializeitem</sv:value>
</sv:property>
<sv:property sv:name="hippo:contentresource" sv:type="String">
<sv:value>cms-dashboard.xml</sv:value>
</sv:property>
<sv:property sv:name="hippo:contentroot" sv:type="String">
<sv:value>/hippo:configuration/hippo:frontend/cms</sv:value>
</sv:property>
<sv:property sv:name="hippo:sequence" sv:type="Double">
<sv:value>902.0</sv:value>
</sv:property>
</sv:node>
<!-- CMS builtin reports -->
<sv:node sv:name="cms-reports">
<sv:property sv:name="jcr:primaryType" sv:type="Name">
<sv:value>hippo:initializeitem</sv:value>
</sv:property>
<sv:property sv:name="hippo:contentresource" sv:type="String">
<sv:value>cms-reports.xml</sv:value>
</sv:property>
<sv:property sv:name="hippo:contentroot" sv:type="String">
<sv:value>/hippo:configuration/hippo:frontend/cms</sv:value>
</sv:property>
<sv:property sv:name="hippo:sequence" sv:type="Double">
<sv:value>902.0</sv:value>
</sv:property>
<sv:property sv:name="hippo:reloadonstartup" sv:type="Boolean">
<sv:value>true</sv:value>
</sv:property>
<sv:property sv:name="hippo:version" sv:type="String">
<sv:value>2.25.03</sv:value>
</sv:property>
</sv:node>
<!-- CMS browser perspective -->
<sv:node sv:name="cms-browser">
<sv:property sv:name="jcr:primaryType" sv:type="Name">
<sv:value>hippo:initializeitem</sv:value>
</sv:property>
<sv:property sv:name="hippo:contentresource" sv:type="String">
<sv:value>cms-browser.xml</sv:value>
</sv:property>
<sv:property sv:name="hippo:contentroot" sv:type="String">
<sv:value>/hippo:configuration/hippo:frontend/cms</sv:value>
</sv:property>
<sv:property sv:name="hippo:sequence" sv:type="Double">
<sv:value>902.0</sv:value>
</sv:property>
</sv:node>
<!-- CMS admin perspective -->
<sv:node sv:name="cms-admin">
<sv:property sv:name="jcr:primaryType" sv:type="Name">
<sv:value>hippo:initializeitem</sv:value>
</sv:property>
<sv:property sv:name="hippo:contentresource" sv:type="String">
<sv:value>cms-admin.xml</sv:value>
</sv:property>
<sv:property sv:name="hippo:contentroot" sv:type="String">
<sv:value>/hippo:configuration/hippo:frontend/cms</sv:value>
</sv:property>
<sv:property sv:name="hippo:sequence" sv:type="Double">
<sv:value>902.0</sv:value>
</sv:property>
</sv:node>

this results in a possibly different order for bootstrapped items, making the bccm tool incorrectly identify changes
