Bring back VDAVideoDecoder (DXVA via D3D9) for old GPUs

[Half-Modern]

Is your feature request related to a problem? Please describe.
Prior to version 110, it's possible to enable GPU video acceleration on old GPUs by using the command line --disable-gpu-driver-bug-workarounds and flags like "Override software rendering". When you play a video (h264), go to chrome://media-internals and it shows that it uses VDAVideoDecoder:

If you use any of backported browsers (Supermium, Thorium based on Supermium and so on), it will show you this:


Looks like they just removed/disabled VDAVideoDecoder with version 110 since it's not targeted at Windows 7 anymore.

Describe the solution you'd like, including relevant patches or source
If you'd be able to bring back VDAVideoDecoder and DXVA with DirectX9, you would:
Possibly enable GPU video acceleration on Windows XP
Enable at least 15 years old GPUs to be able to use their video decoding functionality
Simply, you would become a legend for whose use/have to use a so old PC for obvious reasons.

Additional Notes
To test it yourself, you can either try to find a laptop with Geforce 7-8-9-200-300 series card or find its desktop variant and a motherboard
supports it (IDK if they are compatible with newest motherboards).
I would happily test as well when I have the time for it.
