Deprecate CacheableSupportsMethodInterface in favor of the new getSupportedTypes(?string $format) methods

I don't think this deprecation can be automatically refactored, implementing getSupportedTypes() requires specific application information

The getSupportedTypes() method should return an array where the keys represent the supported types, and the values indicate whether the result of the supports*() method call can be cached or not.

It's been a year since this issue, so these features are either already contributed or not that relevant. Closing for now to respond to specific reports that require an upgrade. Thanks 👍
