Due to the way Java modules work, this requires a JDK change. The core of the issue is that the [service](https://github.com/openjdk/jdk/blob/56aa1e8dc8047cbc29d554889c64beb6eca0b8eb/src/jdk.internal.vm.ci/share/classes/module-info.java#L37) by which HotSpot requests a Graal compilation is defined in JVMCI. Since JVMCI is in the boot layer, the service can only be implemented by a provider in the boot layer and the package defining the service must be exported to the provider's defining module. This export currently targets [`jdk.internal.vm.compiler`](https://github.com/openjdk/jdk/blob/56aa1e8dc8047cbc29d554889c64beb6eca0b8eb/src/jdk.internal.vm.ci/share/classes/module-info.java#L28) and so the binding fails for the new Graal module. To address this, this PR reflects the Graal module ren
 aming, including adjusting the qualified export.
