Filed the `SinceChecker` bug as [JDK-8354921](https://bugs.openjdk.org/browse/JDK-8354921).

Whenever we merge an update of the symbols from the mainline (can happen multiple times between a rampdown and the respective GA) we'll need to first overwrite our symbols with the incoming changes and then run `make/scripts/generate-symbol-data.sh` to update the symbols with CRaC's ones.

Whenever we add a method to the public CRaC Java API we also need to run the script to update the symbols.

I also found [JDK-8345212](https://bugs.openjdk.org/browse/JDK-8345212), which we don't yet have in this fork. It should allow us to continue using `@since TBD` (or `@since CRaC`, or whatever) and the test will pretend like the CRaC API has been added in the current version — we won't need to do the symbols updates. @rvansa  WDYT?
