Add experimental support for post processors

[YuanboXue-Amber]

Which issue, if any, is this issue related to?

Closes #7567

Is there anything in the PR that needs further explanation?

Adding experimental config processors that allows modifying lint results object:

Type:

// config type:
type ConfigProcessors = string[];

// type of each processor object:
type Processor = {
  name: string;
  postprocess: PostProcessFunction;
};

type PostProcessFunction = (result: LintResult) => void;

Usage:

• In config:

  JSON:

  {
    "processors": ["some_module"]
  }

  or multiple processors:

  {
    "processors": ["module_A", "module_B"]
  }

• Example processor:

  export default function myProcessor() {
    return {
      name: 'remap-location',
  
      /** @type {(result: LintResult) => void} */
      postprocess(result) {
        result.warnings.forEach(warning => {
          warning.endLine = warning.endLine === undefined ? warning.line : warning.line + 5;
        });
      },
    };
  }

@YuanboXue-Amber Thanks for the pull request. Can you take a look at my comments?

[YuanboXue-Amber]

[suggest] How about improving the code example to make it closer to real a use-case?

@ybiquitous Do you refer to the example in the configure.md file? I've updated the example there. It is now more aligned with our specific use case, the reason why we needed this feature. Let me know your thoughts.
