qapi/machine: Rename CpuS390* to S390Cpu*, and drop 'prefix'

QAPI's 'prefix' feature can make the connection between enumeration
type and its constants less than obvious.  It's best used with
restraint.

CpuS390Entitlement has a 'prefix' to change the generated enumeration
constants' prefix from CPU_S390_ENTITLEMENT to S390_CPU_ENTITLEMENT.
Rename the type to S390CpuEntitlement, so that 'prefix' is not needed.

Likewise change CpuS390Polarization to S390CpuPolarization, and
CpuS390State to S390CpuState.
