Makefile: define build result directories

Final build results (.elf, .debug, .map) are to be placed under
directory $(objcbfs), the default is:
   $(obj)/cbfs/$(CONFIG_CBFS_PREFIX)/

Intermediate build results (.o, .s, .S, .inc, .ld) that do not have
a clear one-to-one relation to a file under src/ are to be placed
under directory $(objgenerated), the default is:
   $(obj)/generated

Also defines implicit rules for final build results:

  .debug -> .elf and .map
  .elf -> .bin
