Issue:
Inconsistent summary on error count with --message-format=json
### Problem

`cargo check` emits a good summary on error count, but with `--message-format json`, the count number is increased by 1 because it seems to include the error summary itself as a new error. This also influences summary count of clippy in the same way.

As for warning count, the former reports the count, but with json format, no count is reported.

### Steps

Repoducible repo: https://github.com/os-checker/MRE-cargo-error-count

```rust
// src/main.rs
#![deny(warnings)]
fn main() {
    let a = 1;
}
```

```rust
$ cargo check
error: could not compile `cargo-error-count` (bin "cargo-error-count") due to 1 previous error

$ cargo check --message-format json
error: could not compile `cargo-error-count` (bin "cargo-error-count") due to 2 previous errors
```

Note: this inconsistency might be a bit different on warning report

```rust
# with no #![deny(warnings)]
$ cargo check
warning: `cargo-error-count` (bin "cargo-error-count") generated 1 warning

# with no #![deny(warnings)]
$ cargo check --message-format json
# no count reported
```

Pull request description:
fix: correct error count for `cargo check --message-format json`
Hi! This is my first time contributing to Cargo. If there is anything that I need to do, please let me know!
(I'm not sure whether the commit message is aligned with the Cargo's convention. If it doesn't, I'm willing to modify it!)

This PR resolves the issue with incorrect error count and ensures warnings are correctly displayed when using `cargo check --message-format json`.

Fixes #14472
