  [Diagnostics] Don't drop a statically set NoWarningAsError flag during option processing

When a -W<diag> option is given on the command line, and the corresponding diagnostic has
the NoWarnOnError flag set, prevent the flag from being dropped when the severity is reevaluated.
This fixes PR51837.
