monitor: Do not check TARGET_I386 to build 'info sev' command

Browse Source 
This command is filtered at build-time for i386/x86_64 binaries.
By using the recently introduced HMPCommand::arch_bitmask flag
we can filter it at runtime, making it possible to compile
hmp-commands-info.hx once.

Since the method depends on the CONFIG_SEV definition, define it
in its own stub file.
