  [flang-rt] Add implementation for date_and_time on Windows

date_and_time currently returns -HUGE and blank strings on Windows,
which is what the standard says to do when the date and time aren't
available. This patch adds an implementation that provides the actual
values by providing implementations of the posix functions used by the
existing implementation and then piggybacking off of that
implementation.

Note: This also bumps the minimum Windows version supported by flang-rt
to Windows 10, as some of the functions used here are not available in
earlier Windows versions. Since Windows < 10 is out of support by
Microsoft themselves it should be reasonable for flang-rt to drop
support for them.
