hmp-commands-info.hx: Add rST documentation fragments

Add the rST versions of the documentation fragments.  Once we've
converted fully from Texinfo to rST we can remove the ETEXI
fragments; for the moment we need both.

Note that most of the SRST fragments are 2-space indented so that the
'info foo' documentation entries appear as a sublist under the 'info'
entry in the top level list.

Again, all we need to do to put the documentation in the Sphinx manual
is a one-line hxtool-doc invocation.
