Continuation of #47901

Introduce `SYMFONY_DOTENV_PATH` set by DotEnv class and read by the `debug:dotenv` command to contextualize the debug info with the file that was actually parsed.

The custom path can be set in many ways:

- Doing a call to `(new Dotenv())->bootEnv(dirname(__DIR__).'my/custom/path/to/.env');`
- In `composer.json`: `"extra": { "runtime": { "dotenv_path": "my/custom/path/to/.env" }`
- With the env var: `$_SERVER['APP_RUNTIME_OPTIONS'] = ['dotenv_path' => 'my/custom/path/to/.env'];`

The dotenv file can be outside of the `project_dir`.
