Deprecation: #84549 - Deprecate methods in CoreVersionService

Description
The core version service has been refactored to make use of the new REST API available via https://get.typo3.org/v1/api/doc.
Due to that refactoring multiple methods in class 
        Core have been marked as deprecated:
- get- Download - Base - Url - () 
- is- Younger - Patch - Development - Release - Available - () 
- get- Youngest - Patch - Development - Release - () 
- update- Version - Matrix - () 
Impact
Usage of any of these methods will trigger a PHP 
        E_ error.
Affected Installations
Any that use the mentioned methods.
