RFR: 8315566: [JVMCI] deadlock in JVMCI startup when bad option specified

[Doug Simon]

This PR changes `HotSpotJVMCIRuntime.vmEventListeners` to be initialized in the `HotSpotJVMCIRuntime` constructor. This avoids a deadlock that can occur when this list is lazily initialized. Lazily initializing this list has no measurable performance benefit, especially in the context of libgraal.
