assistedIdentifierSeverity

Controls the diagnostic severity when explicit @Assisted("value") identifiers are used on Metro's native @Assisted annotation where the value differs from the parameter name.

This is an initial step toward deprecating explicit assisted identifiers in favor of parameter names. Only meaningful when useAssistedParamNamesAsIdentifiers is true.

Set to DiagnosticSeverity.WARN by default. Eventually it will become a proper deprecation warning, then error, then removed.
