[foreign-memaccess+abi] RFR: 8276647: Remove C2 trivial call intrinsification support [v3]

[Jorn Vernee]

> Hi,
> 
> This patch removes the C2 support for trivial call intrinsification, which is currently unused. (see also the JBS issue for a brief discussion).
> 
> Besides all the code that is removed by this patch, there is one 'logical' change as well: currently we are encoding `VMStorage[]` as `long[]` in `NativeEntryPoint::make`, but this is no longer needed, and I now can pass the `VMStorage[]` to native code directly. This allows removing the `vmstorage_to_vmreg` & `vmStorageToVMReg` function pair. `parse_vmstorage` is used in the native code instead. (see the code changes in NativeEntryPoint.java & nativeEntryPoint.cpp).

> Thanks,
