Doc: Update some links to Microsoft's documentation

The documentation links on `msdn.microsoft.com` and
`msdn2.microsoft.com` now redirect to `docs.microsoft.com`.

Some of the links in the documentation were to those domains.

In particular:

- An `\externalpage` link to the `Mitigating Cross-site Scripting With
HTTP-only Cookies` article.
- An `\externalpage` link to `Microsoft Actibe Accessibility Event
Constants`
- A link to the `RtlGetVersion` function in
`qoperatingsystemversion.cpp`
- A link to the `GetCommandLine` function in `qcoreapplication.cpp`
- A link to the `KNOWNFOLDERID` constant in `qfiledialog.cpp`

While the redirection works, our script to catch broken links on
dev-snapshots builds of the documentation doesn't handle redirection
correctly, reporting it as broken.

Both to appease the broken-links script and to avoid an unneccesary
redirection, the above links were modified to
point to the equivalent address in the new domain.
