Docs/admin-guide/mm/numaperf: increase depth of subsections

Each section of numaperf.rst has zero depth, and therefore be exposed to
the index of admin-guide/mm.  Especially 'See Also' section on the index
makes the document weird.  Hide the sections from the index by giving the
document a title and increasing the depth of each section.
