Fix #78220: Can't access OneDrive folder

As of Windows 1903, when the OneDrive on-demand feature is enabled, the
OneDrive folder is reported as reparse point by `FindFirstFile()`, but
trying to get information about the reparse point using
`DeviceIoControl()` fails with `ERROR_NOT_A_REPARSE_POINT`. We work
around this problem by falling back to `GetFileInformationByHandle()`
if that happens, but only if the reparse point is reported as cloud
reparse point, and only if PHP is running on Windows 1903 or later.

The patch has been developed in collaboration with ab@php.net.

We should keep an eye on the somewhat quirky OneDrive behavior, since
it might change again in a future Windows release.
