feat: add hle_fallback to 9 emulator profiles

Marked files with HLE fallback based on source code analysis:
- desmume: 3 files (NDSSystem.cpp fake BIOS generation)
- dolphin: 31 files (HLE for IPL, DSP, fonts, Wii system)
- pcsx_rearmed: 7 files (psxbios.c full HLE replacement)
- easyrpg: 4 files (RTP and soundfonts optional)
- dosbox_core: all MT-32/soundfont/BASS files
- dosbox_pure: all MT-32/soundfont files
- boytacean: 8 boot ROMs (open-source embedded in binary)
- citra: shared_font.bin only (HLE for font rendering)
- azahar: shared_font.bin only

Not modified (no HLE): beetle_psx, duckstation, ecwolf, emuscv.
