kbuild: move asm-offsets.h rule to ./Kbuild
Currently, MIPS is the only architecture that needs include/generated/asm-offsets.h, but we have got ./Kbuild file now. It is a good reason to move asm-offsets.h rule from arch/mips/Makefile to ./Kbuild and add dummy asm-offsets.c for the other architectures. asm-offsets.h would be useful for all the architectures. This commit does not implement include/generated/bounds.h, but if necessary, it is easy to implement it.
