JDK-8303678: [JVMCI] Add possibility to convert object JavaConstant to jobject.

[tzezula]

This pull request adds a jdk.vm.ci.hotspot.HotSpotJVMCIRuntime#getJObjectValue(HotSpotObjectConstant peerObject) method, which gets a reference to an object in the peer runtime wrapped by the jdk.vm.ci.hotspot.IndirectHotSpotObjectConstantImpl. The reference is returned as a HotSpot heap JNI jobject.
