print_hex(uint8_t) was an early bare-metal helper doing exactly what
hex8() in the freshly-ported hex_print.c does (two-digit hex via
putchar()). hex8() is smaller (asm cp/sbc/daa nibble trick, no LUT)
and consistent with the dec8/hex16/dec16/hex32/dec32 family.
• Replaced print_hex() calls with hex8() in examples/banked and
examples/bankedbg.
• Removed libc/stdio/print_hex.c, dropped its prototype from
sprinter.h and its entry from lib/Makefile.
