target/arm/helper: zcr: Add build bug next to value range assumption
The current implementation of ZCR_ELx matches the architecture, only implementing the lower four bits, with the rest RAZ/WI. This puts a strict limit on ARM_MAX_VQ of 16. Make sure we don't let ARM_MAX_VQ grow without a corresponding update here.
