fix: virtualjaguar notes and refs at v3.10.0

Same four files. A CD BIOS outside the two CRC32 constants is accepted on a plausible run address (libretro.c:5706-5781), and a custom cart boot ROM must be exactly 131072 bytes (libretro.c:6010-6050). core_version follows CORE_BASE_VERSION in the Makefile.

-  The boot ROMs are still compiled in, generated by bin2c, but the core no
-  longer only uses them. Staging moved out of retro_load_game into
-  stage_cart_boot_rom, which reads a file first and falls back to the
-  embedded array (libretro.c:5339-5382). BT_M_SERIES tries jagboot_m.rom in

-  searches six names across the system directory and two subdirectories
