Remove --disable-thread-safety and related code.

Browse Source 
All supported computers have either POSIX or Windows threads, and we no
longer have any automated testing of --disable-thread-safety.  We define
a vestigial ENABLE_THREAD_SAFETY macro to 1 in ecpg_config.h in case it
is useful, but we no longer test it anywhere in PostgreSQL code, and
associated dead code paths are removed.

The Meson and perl-based Windows build scripts never had an equivalent
build option.
