mingw: implement nanosecond-precision file times

We no longer use any of MSVCRT's stat-functions, so there's no need to
stick to a CRT-compatible 'struct stat' either.

Define and use our own POSIX-2013-compatible 'struct stat' with nanosecond-
precision file times.

Note: This can cause performance issues when using Git variants with
different file time resolutions, as the timestamps are stored in the Git
index: after updating the index with a Git variant that uses
second-precision file times, a nanosecond-aware Git will think that
pretty much every single file listed in the index is out of date.
