KVM: Move KVM_REG_SIZE() definition to common uAPI header
Define KVM_REG_SIZE() in the common kvm.h header, and delete the arm64 and
RISC-V versions. As evidenced by the surrounding definitions, all aspects
of the register size encoding are generic, i.e. RISC-V should have moved
arm64's definition to common code instead of copy+pasting.
