Argyrios Kyrtzidis 27a03b19f4 [Support/FileSystem] Add sub-second precision for atime/mtime of sys::fs::file_status on unix platforms
Summary:
getLastAccessedTime() and getLastModificationTime() provided times in nanoseconds but with only 1 second resolution, even when the underlying file system could provide more precise times than that.
These changes add sub-second precision for unix platforms that support improved precision.

Also add some comments to make sure people are aware that the resolution of times can vary across different file systems.
