win32: add (some) long path supportlong_paths

Use the longPathAware manifest entry to handle path lengths above
260.  This requires the LongPathsEnabled registry key to be set
at run-time.

Modify (some) WIN32 API calls to use the wide-character variant.

These features are controlled by the build-time configuration
option FEATURE_LONG_PATHS, which is not enabled by default.
