feat: archive full dolphin-emu/Sys, add DSP/font/IPL paths to pack

dolphin-emu/Sys/ folder (2562 files) from libretro/dolphin Data/Sys. retroarch.yml: DSP firmware (dsp_coef.bin, dsp_rom.bin), fonts (font_western.bin, font_japanese.bin) at dolphin-emu/Sys/GC/ paths. ref: DolphinLibretro/Boot.cpp:72-73, HW/DSPLLE/DSPHost.cpp, HW/EXI/EXI_DeviceIPL.cpp. pack: 452 files, 0 missing.
