    driver: Move -fdiagnostics-urls= early like -fdiagnostics-color= [PR114980]
    
    In GCC 14 we started to emit URLs for "command-line option <option> is
    valid for <language> but not <another language>" and "-Werror= argument
    '-Werror=<option>' is not valid for <language>" warnings.  So we should
    have moved -fdiagnostics-urls= early like -fdiagnostics-color=, or
    -fdiagnostics-urls= wouldn't be able to control URLs in these warnings.
    
    No test cases are added because with TERM=xterm-256colors PR114980
    already triggers some test failures.

            * opts-common.cc (prune_options): Move -fdiagnostics-urls=
            early like -fdiagnostics-color=.
    
    (cherry picked from commit f75806ec63ec1af2d76a194e5fa73e114b2b8857)
