chore(eslint-plugin): rule against invalid paths (#28828)

This is a follow up to #28658, #28772, and #28760. We had to fix multiple places where that file path extended beyond the package itself into other areas of the local repository (that would not be available after packaging). This caused myriad issues at synth time with `file not found` errors.

This PR introduces a linter rule with the following specifications:
- no inefficient paths, i.e. no going backwards multiple times. Ex. `path.join(__dirname, '..', 'folder', '..', 'another-folder')`. This should and can be easily simplified
- no paths that go backwards past a `package.json` file. This should catch the instances we faced next time.

The `yarn lint` command on `aws-cdk-lib` took 51.47s seconds without this new rule and 53.32s seconds with the rule enabled. The difference of ~2 seconds shouldn't be a hindrance in this case but I am happy to look for additional efficiencies in the rule I've written.
