Create the custom block along with all its necessary components for functionality

This work is based on the related issue.

@abhisek, this looks good, tested it and works like advertised.

Before merging i would tag a stable of mautic api 2.0.0, so we can use that, and adjust in the composer.json file here.

And one further note.

"require": {
        "drupal/core": "^10.3||^11",
        "drupal/mautic_api": "2.0.x-dev@dev",
        "mautic/api-library": "^3.1"
    },
    "extra": {
        "patches": {
            "mautic/api-library": {
                "Add support for client credentials grant (see PR: https://github.com/mautic/api-library/pull/269)": "https://patch-diff.githubusercontent.com/raw/mautic/api-library/pull/269.diff",
                "Make the setLogger method on the API class adhere to the LoggerAwareInterface (see PR: https://github.com/mautic/api-library/pull/286/commits/73a92ddc259ca696ce7a6932b127529447e82d17)": "https://github.com/mautic/api-library/commit/73a92ddc259ca696ce7a6932b127529447e82d17.diff"
            }
        }
    }

We don't need to pull in mautic/api-library here, that's done by drupal/mautic_api, also the patches are not needed here, they are in that module, so composer will pick them up from there.

And afterwards i would say go ahead here and tag a 1.0.0 release.
