eclair-analysis: tidy toolchain.ecl configuration and mark Rule 1.1 clean

Browse Source 
Reformat the list of GNU extensions and non-standard tokens used by Xen
in the ECLAIR configuration to make it easier to review any changes to it.

The extension "ext_missing_varargs_arg", which captures the GNU extension that
allows variadic functions and macros not to require at least one named parameter
before C23 has been renamed to "ext_c_missing_varargs_arg" in the current version
of ECLAIR used in CI, therefore this resolves regressions on MISRA C Rule 1.1:

"The program shall contain no violations of the standard C syntax and constraints,
and shall not exceed the implementation's translation limits."

As a result, Rule 1.1 now has no violations and is tagged as such.

Remove two unused configurations, that were already commented out.
