[graalvm-dev] Formal dependency on JVMCI

[Doug Simon]

Hi Chris,

The source truth for the required JVMCI version is in JVMCIVersionCheck.java <https://github.com/oracle/graal/blob/03217a31ee2f8e3fb2b75e9d7b14220d645e5955/compiler/src/org.graalvm.compiler.hotspot/src/org/graalvm/compiler/hotspot/JVMCIVersionCheck.java>.

Where else and in what format would you like that to be declared? Note that with JDK 11 about to be supported, a single JVMCI version number will denote 2 different base JDKs.
