RFR: 8167180: [JVMCI] Exported elements referring to inaccessible types in jdk.vm.ci

[Doug Simon]

I just updated the webrev to adapt a number of jtreg tests to the API changes.

Also, JVMCICompilerFactory, HotSpotVMEventListener and EventProvider are all interfaces now (instead of abstract classes).

The problem is that some of these service types reference other JVMCI types that are not in exported packages as reported by the new lint check. To address this mixing of exported and non-exported types, this webrev introduces a new (meta) service, jdk.vm.ci.services.JVMCIAccess, that is now used to get providers for all other services:
