dd189a354b Fix Stat.ctime docs, and correct its value on Windows
ctime is last file status/metadata change, not creation time. Note that this mistake was not made in the `File.metadata`/`File.Metadata` implementation, which allows getting the actual creation time.

Closes #18290

11a398af3e File.stat: Support detection of Kind.sym_link on Windows
Requires an extra NtQueryInformationFile call when FILE_ATTRIBUTE_REPARSE_POINT is set to determine if it's actually a symlink or some other kind of reparse point (https://learn.microsoft.com/en-us/windows/win32/fileio/reparse-point-tags). This is something that `File.Metadata.kind` was already doing, so the same technique is used in `stat`.

Also, replace the std.os.windows.DeviceIoControl call in `metadata` with NtQueryInformationFile (NtQueryInformationFile is what gets called during kernel32.GetFileInformationByHandleEx with FileAttributeTagInfo, verified using NtTrace).
