chore: record what each platform installs

Each platform's own packages were read at the revision our data pins, for every emulator and core it ships: Batocera, Recalbox, RetroPie, ROCKNIX, Lakka, RetroDECK, RetroBat and EmuDeck. Files a package installs where the emulator reads them are recorded with installed_on, and files a release bundles but a package leaves out with not_bundled_on, so each platform's pack brings what its users lack and nothing they already have. The standalone profiles never checked before were held against their releases the same way. Batocera's imame4all is the mame2000 core. The primary neogeo.zip was a 7.7 KB placeholder no platform pins and no pack served: removed, the real dumps stay in .variants.
