Use LoggerChannelFactoryInterface

Problem/Motivation

The MarketingCloudService class is the Drupal logger but type hinting it as the core implementation instead of the interface. This is an issue when a different implementation is used as it will through an error.

Steps to reproduce

Use a different logger channel factory. An example to follow or use would be the redirect_404 module inside the redirect module.

logger.redirect_404:
    public: false
    class: \Drupal\redirect_404\Render\Redirect404LogSuppressor
    decorates: logger.factory
    arguments: ['@logger.redirect_404.inner', '@config.factory']

Proposed resolution

Change the type hint to use the interface.
