color: enable ANSI support on Windows 10

This will display color if "color.mode=ansi", and default to 'ansi' if the mode
is set to 'auto'.  The 'debugcolor' command also reflects this policy.
Previously, "color.mode=ansi" on Windows printed jibberish around the normal
text.  Using ANSI color is better, as it avoids the normal loss of color when
the default pager is enabled on Windows.  See also issue5570.

When the underlying function fails (e.g. when run on older Windows), 'auto'
still falls back to 'win32'.  Apparently, Microsoft originally had this feature
turned on by default, and then made it opt-in[1].  Therefore, not enabling it
unconditionally seems safer.  Instead, only do it after processing the existing
check for support in a Unix-like environment.

If you can't run the entire testsuite for some reason (it can be
difficult on Windows), please at least run `contrib/check-code.py` on
any files you've modified and run `python contrib/check-commit` on any
commits you've made (for example, `python contrib/check-commit
273ce12ad8f1` will report some style violations on a very old commit).
