Changes includes:
1. Change MSR name:
1. MSR_GOLDMONT_SGXOWNER0 => MSR_GOLDMONT_SGXOWNEREPOCH0
2. MSR_GOLDMONT_SGXOWNER1 => MSR_GOLDMONT_SGXOWNEREPOCH1
2. Keep old MSR definition (MSR_GOLDMONT_SGXOWNER0/1) for compatibility.
1. Define old MSR like below style:
#define MSR_GOLDMONT_SGXOWNER0 MSR_GOLDMONT_SGXOWNEREPOCH0
