Check FFI_* ABI with Autoconf AC_CHECK_DECL (#13552)

Browse Source 
The FFI_* calling conventions are enum constants and AC_CHECK_DECL(S)
can be used to check for their existence in the ffi.h header. This
simplifes the checks and adds a simple AC_CHECK_DECL macro wrapper which
defines the HAVE_FFI_* belonging symbols.
