Documentation/SubmitChecklist: convert it to ReST markup

- use ``foo`` to markup inline literal stuff, effectively making it
  to be presented as a monospaced font when parsed by Sphinx;

- the markup below the title should have the same length as the
  title;

- Fix the list markups, from "1:" to "1)";

- Split item 2 into a separate list for the build options, in order
  to be presented as a list on Sphinx;

 Linux Kernel patch submission checklist
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 Here are some basic things that developers should do if they want to see their
 kernel patch submissions accepted more quickly.
 
 These are all above and beyond the documentation that is provided in
-Documentation/SubmittingPatches and elsewhere regarding submitting Linux
-kernel patches.

-1: If you use a facility then #include the file that defines/declares
+1) If you use a facility then #include the file that defines/declares
    that facility.  Don't depend on other header files pulling in ones
    that you use.

-    candidate for change.

     (Not required for static functions, but OK there also.) Use
     ``make htmldocs`` or ``make pdfdocs`` to check the
     :ref:`kernel-doc <kernel_doc>` and fix any issues.
