load-path: Avoid using file_stat on Windows (bug #59711).
* liboctave/system/oct-time.h, oct-time.cc (octave::sys::file_time): New class
to handle an efficient native file time type per platform.
* libinterp/corefcn/load-path.h (load_path::dir_info::dir_mtime,
load_path::dir_info::dir_time_last_checked): Change type to new class.
* libinterp/corefcn/load-path.cc (subdirs_modified, load_path::dir_info::update,
load_path::dir_info::initialize): Avoid using file_stat on Windows.
