[WIP][FEATURE] Make DeepL translation TSconfig configurable

[calien666]

Following the example of TYPO3's Page TSConfig settings, DeepL should also allow settings to be made via Page TSConfig. This makes it easier for integrators to use and provides a better overview, as the settings are made in the same way as for TYPO3 Core.

New:

mod {
    web_layout {
        localization {
            # default, set to 0 to disable DeepL Translate
            enableDeeplTranslate = 1
            # default, set to 1 to disable core translation options
            disableCoreTranslation = 0
        }
    }
}
