KVM: x86: Explicitly #define the VCPU_REGS_* indices
Declaring the VCPU_REGS_* as enums allows for more robust C code, but it
prevents using the values in assembly files. Expliciting #define the
indices in an asm-friendly file to prepare for VMX moving its transition
code to a proper assembly file, but keep the enums for general usage.
