Add possibility to configure a custom ExecutionContextSerializer in BatchAutoConfiguration

See #38234

I would like to auto configure a Jackson2ExecutionContextStringSerializer if enables by a use property.

    @Bean
    @ConditionalOnMissingBean(ExecutionContextSerializer.class)
    @ConditionalOnProperty(prefix = "spring.batch.jdbc", name = "use-jackson2-context-serializer", havingValue = "false")
    public Jackson2ExecutionContextStringSerializer executionContextStringSerializer() {
        return new Jackson2ExecutionContextStringSerializer();
    }

@fmbenhassine WDYT?

There is no need for a property, the presence of a bean of type ExecutionContextSerializer is enough to be picked up by Boot, otherwise a DefaultExecutionContextSerializer should be used. The last PR update LGTM.
