Morph PV RDMSR/WRMSR hypercall to EXIT_REASON_MSR_{READ,WRITE} and
wire up KVM backend functions.
For complete_emulated_msr() callback, instead of injecting #GP on error,
implement tdx_complete_emulated_msr() to set return code on error. Also
set return value on MSR read according to the values from kvm x86
registers.
