Include stdbool.h without checking with autoconf
As reported in <https://bugs.ruby-lang.org/issues/21340>, older autoconf
have an AC_HEADER_STDBOOL that's incompatible with C23. Autoconf 2.72
fixed the macro, but also mentions that it's obsolescent since all
current compilers have this header.

Since we require C99 [1] and VS 2015 [2], we might actually be able take
that suggestion and include stdbool.h without a check. I want to try
this on rubyci.org and will revert if this cause any issues. Not
touching AC_HEADER_STDBOOL in configure.ac for now.
