include: Make stdbool.h a separate file

This patch moves the traditional POSIX stdbool.h definitions out from
stdint.h into their own file. This helps for using these definitions in
commonlib code which may be compiled in different environments. For
coreboot everything should chain-include this stuff via types.h anyway
so nothing should change.
