KVM: x86: Update __get_sregs() / __set_sregs() to support SEV-ES

Since many of the registers used by the SEV-ES are encrypted and cannot
be read or written, adjust the __get_sregs() / __set_sregs() to take into
account whether the VMSA/guest state is encrypted.

For __get_sregs(), return the actual value that is in use by the guest
for all registers being tracked using the write trap support.

For __set_sregs(), skip setting of all guest registers values.
