feat: profile opera's built-in Opera Boot ROM

Browse Source 
Upstream compiles Opera Boot into the core as the default BIOS and reads opera-boot.bin from the system directory. Every retail BIOS becomes optional; opera-boot.bin is collected from the opera-boot release, identical to the embedded image.

Opera is the libretro port of the 4DO/FreeDO 3DO Interactive Multiplayer emulator.
The core requires exactly one system BIOS ROM (rom1) selected via the opera_bios
core option. BIOS files are loaded from the system directory with
read_file_from_system_directory() and byteswapped on little-endian hosts.
The core will not start without a valid BIOS ROM.
The system ROM (rom1) is chosen by the opera_bios core option. Its default is
Opera Boot, an open boot ROM (trapexit/opera-boot) compiled into the core as a
zlib stream and inflated at load, so the core starts with no file at all. The
option lists the built-in ROM first, then each BIOS file physically present in
the system directory; a file is read with read_file_from_system_directory()
and byteswapped on little-endian hosts.
The user selects which BIOS to use from the core option dropdown, which only
lists BIOS files physically present in the system directory. Any single BIOS
from the list below is sufficient to run games from its region.
opera-boot.bin is the same Opera Boot image read from the system directory
("Opera Boot (System)"), for a newer build than the one compiled in.
Kanji font ROMs (rom2) are optional and only needed for Japanese text rendering.
They are loaded via opera_lr_opts_set_font() and selected via opera_font core option.
All BIOS files are exactly 1 MB (1048576 bytes) except 3do_arcade_saot.bin (512 KB)
and panafz1-kanji.bin (933636 bytes).
All BIOS files are exactly 1 MB (1048576 bytes) except opera-boot.bin (128 KB),
