feat: declare the upstream names of 26 profiles

Each name is attested by a buildbot .info file, a hardware target core
list or an ES-DE find rule. Two of them resolved to no profile at all:
dosbox_staging, declared by Batocera on three targets, and
freeintvtsoverlay, shipped as FreeIntvTSOverlay_libretro.info.

vba_m keeps no cores list: no upstream calls it that. It is a legacy key
folded into vbam, which already carries the buildbot name vba-m.
