[feature] build_modules in 2.0 fails with error instead of a nice migration warnings

[prince-chrismc]

deprecated build_modules causes 2.0 to fail where it should output a warnings -- This can be see with the cpp_info.names and cpp_info.user_info attributes but not this one.

Post-op from playing with #12555

It would also be nice to make the warning optional with a conf setting... It's extremely noisy 🙊

@prince-chrismc was a conf setting ever introduced to control the warning messages?
