Experimental TaskHashPlanInspector (#27809)

## Current Behavior
<!-- This is the behavior we have today -->

There is no easy way to inspect the hash plan for a task.

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->

There is a `TaskHashPlanInspector` which can be used to provide details
about the hash plan for a task.

## Example Usage

```js
const { createProjectGraphAsync } = require('@nx/devkit');
const { HashPlanInspector } = require('nx/src/hasher/hash-plan-inspector');

(async () => {
  const graph = await createProjectGraphAsync();
  const hashPlanInspector = new HashPlanInspector(graph);
  await hashPlanInspector.init();
  const target = {
    project: 'nx',
    target: 'build-native',
  };
  console.log(
    JSON.stringify(hashPlanInspector.inspectTask(target), null, 2)
  );
})();
```
