This MR adds a very basic implementation of `IPropertyDescription` for system defined properties (i.e, the ones in \<propkey.h\>). This is needed to support the [`Properties`](https://learn.microsoft.com/en-us/uwp/api/windows.devices.enumeration.deviceinformation.properties?view=winrt-26100) method for `IDeviceInformation` in Windows.Devices.Enumeration (!6874).

Windows 10 and 11 introduce the timeout.exe command. This is a similar program with same argument options

v20: timeout: add minimal test suite
timeout: Windows 10 introduce the timeout command

The tests aren't really tested though (they partially require interactive mode
and they caused lag issues on one person's machine).

Some things to test:
* could we use sample allocator unconditionally? In other words, is it possible to get SVR used when no device manager was provided;
* EVR has a circular buffer logic, so maybe we could copy from there;
* it would be great if we could get rid of locking sample buffer for copies, and that should be possible if we always have d3d samples.

I find this hard to understand. We'll need to document what's happening. For example, why does this check one more sample at all? Is that because buffer size is 2, or we always would check the adjacent one.

That's something else, unrelated to SVR work?

I think you can use MFSTREAMSINK_MARKER_ENDOFSEGMENT for this. The way you did it sort of bypasses normal session flow, there is potentially unknown number of pending samples in the pipeline once MEEndOfPresentation is received. This is only a problem if for some reason earlier node somehow requests more times than the sink. ENDOFSEGMENT is already used in EVR, and that seems to work.
