docs/about: Update the support statement for Windows

Browse Source 
Our support statement for Windows currently talks about "Vista / Server
2008" - which is related to the API of Windows, and this is not easy
to understand for the non-technical users. Additionally, glib sets the
_WIN32_WINNT macro to 0x0601 already, which indicates the Windows 7 API,
so QEMU effectively depends on the Windows 7 API, too.

Thus let's bump the _WIN32_WINNT setting in QEMU to the same level as
glib uses and adjust our support statement in the documentation to
something similar that we're using for Linux and the *BSD systems
(i.e. only the two most recent versions), which should hopefully be
easier to understand for the users now.

And since we're nowadays also compile-testing QEMU with MSYS2 on Windows
itself, I think we could mention this build environment here, too.

Windows
-------
The project supports building with current versions of the MinGW toolchain,
hosted on Linux (Debian/Fedora).
The project aims to support the two most recent versions of Windows that are
still supported by the vendor. The minimum Windows API that is currently
targeted is "Windows 7", so theoretically the QEMU binaries can still be run
on older versions of Windows, too. However, such old versions of Windows are
not tested anymore, so it is recommended to use one of the latest versions of
Windows instead.
The version of the Windows API that's currently targeted is Vista / Server
2008.
The project supports building QEMU with current versions of the MinGW
toolchain, either hosted on Linux (Debian/Fedora) or via MSYS2 on Windows.
