arch-x86: X86ISA default vector_string to HygonGenuine

This commit,, changed the
default 'vendor_string' for the 'X86ISA' SimObject from 'M5 Simulator'
and 'AuthenticAMD'. Unforunately due to an issue highlighted here: we cannot use the
'AuthenticAMD'. Therefore, this change updates the default vector_string
to HygonGenuine.

The HygonGenuine is simple but works.
