OvmfPkg/ResetVector: Removing SEV-ES CPUID bit check
The SEV-ES bit of Fn800-001F[EAX] - Bit 3 is used for a host to
determine support for running SEV-ES guests. It should not be checked by
a guest to determine if it is running under SEV-ES. The guest should use
the SEV_STATUS MSR Bit 1 to determine if SEV-ES is enabled. This check
was not part of the original SEV-ES support and was added in
a91b700e38. Removing the check makes this code consistent with the
Linux kernel
Fixes: a91b700e38 ("Ovmf/ResetVector: Simplify and consolidate the SEV features checks")
