Suppress "load-only" warning for global options

this doesn't test the load-only code, and if I add testoption .usage=load then the duplicate load still produces a warning:

LaTeX Warning: Package "testpackage" has already been loaded: ignoring
(LaTeX)        load-time option "testoption".

Thanks - fixed

[davidcarlisle]

using classoptionlist here rather than one of the versions that's been filtered to drop the values (eg for unused option warnings) seems a bit suspect. If I change the 1606 test file to have

\documentclass[testoption=?]{article}

Then the warning comes back for duplicate loads

LaTeX Warning: Package "testpackage" has already been loaded: ignoring
(LaTeX)        load-time option "testoption".

which doesn't seem quite right?

If I test in this PR

\begin{filecontents*}[overwrite]{testpackage.sty}
\ProvidesExplPackage{testpackage}{2025-02-04}{}{}
\keys_define:nn { testpackage }
  {
    testoption .code:n = { \def \testmacro { #1 } } ,
    testoption .usage:n = { load }
  }
\ProcessKeyOptions [ testpackage ]
\endinput
\end{filecontents*}

\input{test2e}

\documentclass[testoption]{article}
\usepackage[testoption=false]{testpackage}
\usepackage[testoption=true]{testpackage}
\show\testmacro
\END 

Then I get no warning about an ignored load option. But with
\documentclass[testoption=false]{article} or \documentclass[testoption=true]{article}
I get two warnings (also in the current implementation).

OK, I'll think of a second generation plan
