Fix building pycore_bitutils.h internal header on old clang version
without __builtin_bswap16() (ex: Xcode 4.6.3 on Mac OS X 10.7).

Add a new private _Py__has_builtin() macro to check for availability
of a preprocessor builtin function.

Are you going to replace all of the __has_builtinlogic into the newly added macro with the sperate PRs?

I saw that __has_builtin() is used to support the new macOS version, but I don't plan to change this code. This code is new and fragile, and prefer to let someone else modifying it, but I don't think that it's worth it ;-) The practical issue is also that I cannot test such change on the new macOS.
