        src/sys/arch/x86/x86: spectre.c x86_machdep.c

Log Message:
Several changes:

 - Move the sysctl initialization code into spectre.c. This way each
   variable is local. Rename the variables, use shorter names.

 - Use mitigation methods for SpectreV4, like SpectreV2. There are
   several available on AMD (that we don't support yet). Add a "method"
   leaf.

 - Make SSB_NO a mitigation method by itself. This way we report as
   "mitigated" a CPU that is not affected by SpectreV4. In this case,
   of course, the user can't enable/disable the mitigation. Drop the
   "affected" sysctl leaf.
