Makefile.debug: set -g unconditional on CONFIG_DEBUG_INFO_SPLIT
Dmitrii, Fangrui, and Mashahiro note: Before GCC 11 and Clang 12 -gsplit-dwarf implicitly uses -g2. Fix CONFIG_DEBUG_INFO_SPLIT for gcc-11+ & clang-12+ which now need -g specified in order for -gsplit-dwarf to work at all. -gsplit-dwarf has been mutually exclusive with -g since support for CONFIG_DEBUG_INFO_SPLIT was introduced in commit 866ced95 ("kbuild: Support split debug info v4") I don't think it ever needed to be.
