RFR: 8306111: PPC64: RT call after thaw with exception requires larger ABI section [v2]

[Richard Reingruber]

> After thawing a frame to forward an exception, we call `SharedRuntime::exception_handler_for_return_address()`. The frame just thawed lacks the required `frame::native_abi_reg_args` though. It is only equipped with `frame::java_abi`. This change pushes a new frame with the required ABI.
> 
> Furthermore the change enables `VMContinuations` by default also for PPC64 big endian.
> 
> Testing: jdk_loom on little and big endian.
