fix: reprofile virtualxt from its C core

Browse Source 
The profile described an Odin edition no branch carries any more. At
the pinned commit core.c embeds VXTBIOS, VXTX and the EGA BIOS, never
asks for the system directory, and writes its FreeDOS image to the
save directory; an INI machine can load a ROM from a path it names.

# All BIOS ROMs are embedded at compile time via Odin's #load() directive.
# No external files are loaded from system_dir in standard operation.
# The BIOS ROMs are compiled in: core.c includes headers generated from
# bios/vxtbios.bin, bios/vxtx.bin and bios/egabios.bin, and hands them to the
# ROM peripherals with vxt_rom_set_data. The core never asks for the system

notes:
bios_approach: >
All BIOS ROMs embedded at compile time via Odin #load() directive.
Open-source replacements: GLaBIOS (GPL), Turbo XT BIOS 3.1, vgabios.
No proprietary IBM PC/XT BIOS needed.
VXTBIOS, the VXTX disk extension and the EGA BIOS are embedded. A machine
described by an INI file can load a ROM from a path the INI names, read
through the frontend VFS as written. With no content the core writes its
embedded FreeDOS hard disk image to virtualxt_default.img in the save
directory and boots it.
