fix: correct type and path fields across 58 emulator profiles

49 libretro cores had type: game/utility/test instead of type: libretro,
breaking the all_libretro filtering in resolve_platform_cores and
excluding them from platform packs (e.g. cannonball missing from
RetroArch). core_classification already carries the descriptive role.

9 profiles with subdirectory-loading cores (cannonball/, nxengine/,
Citra/sysdata/, mame2003/, mame2003-plus/, mame2010/) now have path:
fields so cross-reference places files at the correct destination.

resolve_local_file now tries basename when name contains a path
separator (e.g. res/tilemap.bin -> tilemap.bin), fixing resolution
of files with subdirectory names.
