Move configure --disable-float8-byval to pg_config_manual.h
This build option was once useful to maintain compatibility with
version-0 functions, but those are no longer supported, so this option
is no longer useful for end users. We keep the option available to
developers in pg_config_manual.h so that it is easy to test the
pass-by-reference code paths without having to fire up a 32-bit
machine.
