Issue title: Lint/EmptyFile causes error when I run RuboCop with `--format=json`
 Issue body: The combination with `Lint/EmptyFile` and the `--format=json` option seems to cause error. Perhaps, this relates the `PseudoSourceRange` here, but I'm not sure how to fix the problem.

---

## Expected behavior

RuboCop finishes the analysis without error.

## Actual behavior

Error is thrown when processing `Lint/EmptyFile`.

## Steps to reproduce the problem

You can reproduce this problem with [this](https://github.com/yykamei/tmp-rubocop-json-formatter-issue) repository.

1. Clone [this](https://github.com/yykamei/tmp-rubocop-json-formatter-issue) repository and move on to the cloned directory
2. Run `bundle install` (Maybe, you should set up your Ruby with rbenv)
3. Run `bundle exec rubocop --cache=false --format=json a.rb`

## RuboCop version

Master: 03e83a2b234feaa025333345a0c115751cc4a35e

```
$ [bundle exec] rubocop -V
0.91.0 (using Parser 116.69.203.115, rubocop-ast 0.4.0, running on ruby 2.7.1 x86_64-linux)
```

 Comments: 
 Comment 0: This issue will happen for any cop that registers an offense for a file rather than for a code range. 

I have a quick fix for this, however I'd like to discuss the potential impact and how exactly we'd like to fix this. The problem is straight forward, the formatter references `last_line` and `last_column` and those values aren't defined for a file based offense. 

The easiest solution seems to be to add `last_line` and `last_column` to the `PseudoSourceRange` struct, and then define the values to 0. Do we want to fix the issue this way? Should we ensure that we define all of the public methods from `Offense` in `PseudoSourceRange`?

 Comment 1: I found a workaround to avoid the error: disabling the `Lint/EmptyFile` cop.

via a configuration file:

```yaml
AllCops:
  NewCops: enable

Lint/EmptyFile:
  Enabled: false
```

via CLI:

```shell
rubocop --enable-pending-cops --except=Lint/EmptyFile
```

This error occurs only on cops using the `RuboCop38d1:d2b4:3d06:83e8:96a5:8c2:893d:aba5op38d1:d2b4:3d06:83e8:96a5:8c2:893d:aba5se#add_global_offense` method. Because `Offens38d1:d2b4:3d06:83e8:96a5:8c2:893d:aba5NO_LOCATION` is used only in the `#add_global_offense` method.

https://github.com/rubocop-hq/rubocop/blob/aa7d8d454de563f081e783c967b8fcceb4c94202/lib/rubocop/cop/base.rb#L106-L111

The cops are: `Lint/EmptyFile` and `Lint/Syntax`

https://github.com/rubocop-hq/rubocop/blob/aa7d8d454de563f081e783c967b8fcceb4c94202/lib/rubocop/cop/lint/empty_file.rb#L29

https://github.com/rubocop-hq/rubocop/blob/aa7d8d454de563f081e783c967b8fcceb4c94202/lib/rubocop/cop/lint/syntax.rb#L31

`Lint/Syntax` is a basic cop, so I think we could keep it enabled in most cases.

For third-party cops, I found the `Itamae/RecipePath` cop uses the `#add_global_offense` method.
So, `rubocop-itamae` users may need to disable also `Itamae/RecipePath`:

https://github.com/sue445/rubocop-itamae/blob/e724cd0ffab96c1472455bc7ec733ed11b9d3ad2/lib/rubocop/cop/itamae/recipe_path.rb#L30



 Comment 2: I retested on master - no errors.
Can you verify that was fixed by https://github.com/rubocop-hq/rubocop/pull/8676?

You, probably, would need to clear local rubocop cache, by `rm -rf ~/.cache/rubocop_cache` before checking.
 Comment 3: > The easiest solution seems to be to add `last_line` and `last_column` to the `PseudoSourceRange` struct, and then define the values to 0. Do we want to fix the issue this way?

👍

> Should we ensure that we define all of the public methods from `Offense` in `PseudoSourceRange`?

Not sure. Being lazy I'd do it on a need only basis.

 Comment 6: Hi, I cannot update RuboCop to the latest version due to thi issue, I'd like to really fix it.

The patch in <https://github.com/rubocop-hq/rubocop/issues/8718#issuecomment-692723452> by @rrosenblum seems good to me.

Can I open a new PR to apply the patch? Or, is there anything else to consider? 
 Comment 7: @ybiquitous Yes, the patch that I mentioned can be applied and opened as a PR to fix this. Maybe there is some sort of test case that we'll want to introduce to show the fixed behavior. Feel free to create the PR, otherwise I can take care of it.
 Comment 8: @rrosenblum Thanks for your help! I've opened the PR #8823.
