qemu-options.hx: Fix formatting of -machine memory-backend option 

The documentation of the -machine memory-backend has some minor
formatting errors:
 * Misindentation of the initial line meant that the whole option
   section is incorrectly indented in the HTML output compared to
   the other -machine options
 * The examples weren't indented, which meant that they were formatted
   as plain run-on text including outputting the "::" as text.
 * The a) b) list has no rst-format markup so it is rendered as
   a single run-on paragraph

Fix the formatting.

Enables or disables ACPI Heterogeneous Memory Attribute Table
(HMAT) support. The default is off.
``memory-backend='id'``
``memory-backend='id'``
An alternative to legacy ``-mem-path`` and ``mem-prealloc`` options.
Allows to use a memory backend as main RAM.
For example:
::
-object memory-backend-file,id=pc.ram,size=512M,mem-path=/hugetlbfs,prealloc=on,share=on
-machine memory-backend=pc.ram
-m 512M
-object memory-backend-file,id=pc.ram,size=512M,mem-path=/hugetlbfs,prealloc=on,share=on
-machine memory-backend=pc.ram
-m 512M
Migration compatibility note:
a) as backend id one shall use value of 'default-ram-id', advertised by
machine type (available via ``query-machines`` QMP command), if migration
to/from old QEMU (<5.0) is expected.
b) for machine types 4.0 and older, user shall
use ``x-use-canonical-path-for-ramblock-id=off`` backend option
if migration to/from old QEMU (<5.0) is expected.
