include/stdbool: Don't unconditionally typedef bool

When compiling with the C23 standard, bool, true, and false are
pre-defined by the language, so defining them in stdbool.h isn't allowed.
This fixes the following error:
src/include/stdbool.h:6:17: error: two or more data types in declaration specifiers
    6 | typedef _Bool   bool;
      |                 ^~~~
src/include/stdbool.h:6:1: error: useless type name in empty declaration [-Werror]
    6 | typedef _Bool   bool;
      | ^~~~~~~
