fix: split the np2 V98 font from font.bmp

NP2kai and meowPC98 read font.bmp (PC-98 bitmap) and FONT.ROM (V98) as
separate files, each through its own reader (NP2kai font/font.c:192-195,
meowPC98 font/font.c:180-181). The V98 names hung on font.bmp as aliases
let a collection without font.bmp serve the PC-88 2 KB font.rom there.
FONT.ROM is now its own entry, at least 0x46800 bytes (fontv98.c:8, 51).

Manifests: np2/FONT.ROM and np2kai/FONT.ROM are added where the platform
did not declare them, served by the V98 font bios/NEC/PC-98/font.rom.
