Subject: [PATCH 16/24] WIP: Fix build with GCC 15 as host compiler

GCC 15 now considers the unterminated-string-initialization warning as
part of -Werror by default. Coreboot compiles host utilities with the
system compiler, which results in getting this error in some files.

Mark a hexadecimal translation table in cbfstool code as "nonstring" to
avoid the warning-turned-error.

The bios log prefixes are non-null-terminated as well, but I couldn't
figure out how to mark them as non-strings. Temporarily disable the
warning with a pragma to avoid the error. That pragma causes an error on
GCC 14, so disable pragma warnings along with it to avoid that as well.
