Abdessamad Derraz 7cb0e67eb6 feat: profile the Batocera and Recalbox LRPS2
Batocera 43.1 builds libretro/ps2 at 416291a with 001.bios-dir.patch and
Recalbox 10.1.1 builds it at 9485a53 with 0001-recalbox-paths.patch. Both
patches move the BIOS scan from pcsx2/bios to ps2, and Recalbox also moves
the data root to system/ps2. Each build gets its own built_by profile:
lrps2-416291a under Batocera's pcsx2 name, lrps2-9485a53 under Recalbox's
ps2 name.

A platform's own build now answers for its own build mode only on a
dual_mode_cores name, so Batocera keeps standalone PCSX2 beside its
libretro build.

notes: |
Batocera installs the build as pcsx2_libretro.so (Batocera
package/batocera/emulators/retroarch/libretro/libretro-ps2/libretro-ps2.mk:35-36)
and launches it as the libretro core pcsx2 of the ps2 system (Batocera
package/batocera/emulationstation/batocera-es-system/es_systems.yml:2293-2294).
The library version is the short commit hash git reports at build time
(cmake/BuildParameters.cmake:4-9, libretro/main.cpp:1423-1427).
Its patch moves the BIOS scan from pcsx2/bios to ps2 below the system
directory (libretro/main.cpp:1806) and the BIOS folder default to
/userdata/bios/ps2, the same folder on Batocera (pcsx2/Pcsx2Config.cpp:1042).
The data root stays system/pcsx2, so resources are read from
pcsx2/resources and memory cards are written to pcsx2/memcards
(libretro/main.cpp:1910-1912).
BIOS detection is filename-agnostic: ps2/ is scanned for any file between
4 and 8 MB with a RESET and a ROMVER romdir entry, no hash is checked, and
the list fills the pcsx2_bios core option whose default is the first BIOS
found (libretro/main.cpp:1800-1838). retro_load_game refuses to start when
no BIOS was found (libretro/main.cpp:1927-1931). The companion files take
their path from the selected BIOS.
The DEV9 hard disk image is user storage the core creates, not a file to
obtain.
