[PATCH] (file_path_special) Remove 33 unused FILE_PATH_* macros

These macros were defined but had no consumer anywhere in the in-scope
tree (verified after excluding deps/, libretro-common/, libretro-db/,
tests-other/, samples/, and vendored SDK trees). The list:

  Extension constants for image/audio formats RetroArch reads through
  generic file APIs rather than format-specific paths:
    FILE_PATH_MP3_EXTENSION, FILE_PATH_FLAC_EXTENSION,
    FILE_PATH_OGG_EXTENSION, FILE_PATH_WAV_EXTENSION,
    FILE_PATH_MOD_EXTENSION, FILE_PATH_S3M_EXTENSION,
    FILE_PATH_XM_EXTENSION, FILE_PATH_JPEG_EXTENSION,
    FILE_PATH_BMP_EXTENSION, FILE_PATH_TGA_EXTENSION,
    FILE_PATH_JPG_EXTENSION

  Patch-format extensions handled generically by the patch loader:
    FILE_PATH_UPS_EXTENSION, FILE_PATH_IPS_EXTENSION,
    FILE_PATH_BPS_EXTENSION, FILE_PATH_XDELTA_EXTENSION

  Archive extensions handled by libretro-common's archive_file:
    FILE_PATH_ZIP_EXTENSION, FILE_PATH_7Z_EXTENSION

  Shader-preset extensions; the consumer in
  gfx/video_shader_parse.c:video_shader_get_preset_extension uses bare
  string literals rather than these macros:
    FILE_PATH_CGP_EXTENSION, FILE_PATH_GLSLP_EXTENSION,
    FILE_PATH_SLANGP_EXTENSION

  Other dead extension constants:
    FILE_PATH_AUTO_EXTENSION, FILE_PATH_OPT_EXTENSION,
    FILE_PATH_RTC_EXTENSION, FILE_PATH_LPL_EXTENSION_NO_DOT,
    FILE_PATH_RDB_EXTENSION_NO_DOT, FILE_PATH_EVENT_LOG_EXTENSION,
    FILE_PATH_LOCK_EXTENSION, FILE_PATH_STANDALONE_EXEMPT_EXTENSION

  Dead URL/playlist constants:
    FILE_PATH_INDEX_EXTENDED_URL, FILE_PATH_NETPLAY_ROOM_LIST_URL,
    FILE_PATH_RETROACHIEVEMENTS_URL, FILE_PATH_LUTRO_PLAYLIST,
    FILE_PATH_NUL

The header file_path_special.h is internal (not exposed via libretro.h)
and is included only by RetroArch's own .c files; removing these macros
is safe within the tree. The bare string literals these macros would
have parameterised continue to work as before.
