smbios: build legacy mode code only for 'pc' machine

basically moving code around without functional change.
And exposing some symbols so that they could be shared
between smbbios.c and new smbios_legacy.c

plus some meson magic to build smbios_legacy.c only
for 'pc' machine and otherwise replace it with stub
if not selected.
