This MR modifies winegstreamer to match Windows behaviour in that: 1. the video decoders will output the PTS and duration of the input sample (if provided); and 2. the WMV decoder will set any value not provided to zero
It also adds support for supplying a DTS value to the MFTs.
I've marked this as draft as it fixes the tests in MR !7563 (in addition to fixing some existing `test_wmv_decoder` tests). Also, as demonstrated in MR !7569, our demuxers output different timestamps to Windows. This change will result in those different timestamps being forwarded from the decoder. So we may also want to address that difference prior to accepting this MR.
-- v4: winegstreamer: Use provided PTS and duration in video_decoder. mf/tests: Add negative timestamp tests for h264.

When testing these changes with FFmpeg as the demuxer, I found FFmpeg can produce negative PTS and DTS. And then on testing Windows, I discovered that Windows supports negative PTS and DTS, however, gstreamer does not.
So I've made some adjustments to this MR: 1. To add tests for negative PTS and DTS; and 2. To convert PTS and DTS to be zero or above on input to gstreamer and then convert back the output so that our MFTs can support negative values

Are negative timestamps encoded in media data directly?
P.S. we'll need someone to review winegstreamer parts.

This is in the MFT, which can be used by the application directly. In theory, they can assign any value they want (which is how I test the negative values on Windows).
But in terms of media data, I'll use the MPEG4 container as an example (as that's the one where I saw FFmpeg produce negative values). You get given three values/tables: 1. [Media Time](https://developer.apple.com/documentation/quicktime-file-format/edit_list_at...); 2. [Time to Sample](https://developer.apple.com/documentation/quicktime-file-format/time-to-samp...); and 3. [Composition Offset](https://developer.apple.com/documentation/quicktime-file-format/composition_...)
The composition offset is only used when you have a codec that needs decoding in a different order than presentation. For example, H.264 which uses B-Frames.
And it seems Windows, GStreamer and FFmpeg all use these values differently and produce different results.
As an example, say we have: 1. Media Time = 0.666666s 2. Time to Sample 1 = 0s 3. Composition Offset for Sample 1 = 0.333333s
DTS is calculated as PTS minus composition offset.
Windows asserts, due to a Media Time of 0.666666s, then that will be the first PTS: ``` PTS = 0.666666s, DTS = 0.333333 ```
GStreamer asserts that the first DTS will be 0s: ``` PTS = 0.333333s, DTS = 0s ```
FFmeg assets that the first PTS will be 0s: ``` PTS = 0, DTS = -0.333333s ```
In addition, I've seen FFmpeg produce a negative PTS on audio, but I'll have to double check the code to see how it got there. But I did note a couple of possibilities: 1. The value was the negative value of Media Time; 2. The value was the negative value of the duration, and the packet was flagged with `AV_PKT_FLAG_DISCARD`
