Add DEBUG_INFO_REDUCED as a kernel config option and remove it from the
kernel configs. This is in preparation of the upcoming option to enable
BTF typeinfo, which is incompatible with DEBUG_INFO_REDUCED.

This will compile your kernel and modules with debug information.

+ If you say Y here gcc is instructed to generate less debugging
+ information for structure types. This means that tools that
+ need full debugging information (like kgdb or systemtap) won't
+ be happy. But if you merely need debugging information to
+ resolve line numbers there is no loss. Advantage is that
+ build directory object sizes shrink dramatically over a full
+ DEBUG_INFO build and compile times are reduced too.
