feat: update 47 emulator profiles with core_classification and fixes

add core_classification, cores, upstream fields. fix false aliases
(fixnes, fsuae, gearboy, higan_sfc, higan_sfc_balanced, potator,
quicknes). add new profiles (fbneo_neogeo, flycast_gles2,
genesis_plus_gx_wide). remove verbose notes and disclaimers.
