Enable ifunc checks on FreeBSD 12+

This was disabled in 2019 due to problems reported in FreeBSD 11. The original
report (PHP bug 77284) includes a comment that FreeBSD 12 worked - which also
happens to be the first version ifunc use appeared in libc.

Remove obsolescent AC_TYPE_SIZE_T (#12719)

The macro checks for existence of size_t in <stddef.h> otherwise it sets
it to 'unsigned int'. The size_t is part of C89 standard and all
platforms should have it. Macro is also marked to be made obsolete in
the future versions of Autoconf.

At this point there is still AC_FUNC_ALLOCA in PHP's configure.ac which
uses AC_TYPE_SIZE_T under the hood so the check is still done there in
the meantime.

On riscv64 require libatomic if actually needed

clang and newer gcc releases support byte-sized atomic accesses on
riscv64 through inline builtins. In both cases the hard dependency on
libatomic added by GH-11321 isn't useful.

Stop using AC_CHECK_LIB() which is too naive to notice that libatomic
isn't needed. Instead, PHP_CHECK_FUNC() will retry the check with -latomic
if required.

Remove check for time.h and HAVE_TIME_H (#11726)

The `<time.h>` header file is part of the standard C89 headers [1] and
on current systems can be included unconditionally.

The conditional include based on Windows is there so the win32/time.h
can be included on other places when needed.
