RFR: 8346101: [JVMCI] Export jdk.internal.misc to jdk.graal.compiler

[Volker Simonis]

In the past, the Graal Compiler used `sun.misc.Unsafe` but these usages were recently changed to `jdk.internal.misc.Unsafe` [1]. We should therefor export `jdk.internal.misc` to `jdk.graal.compiler` which is an upgradeable module in the JDK.

[1] Remove sun.misc.Unsafe plugins (https://github.com/oracle/graal/commit/5c67d1a6eb8ecf717)
