Same as the previous patch, but avoids assigning from a const& and skips
tests which shouldn't run on Windows 7. PS#1 is take #2, all later patch
sets are the new one.

---- [ Original Description Below ] ----

Does the following:
- Internalizes h264 and min resolution details.
- Sets the minimum resolution to 64,64 for both decoders.
- Only loops through the video device profiles once.
- Switches away from an std::pair to a named struct.
- Adds AV1 GUID values and uses them in DXVA decoder.
- Stops D3D11VideoDecoder for enumerating unsupported profiles.
- Stops using the DXVA2_Intel_ModeH264_E for enumeration.
- Gives all resolution tests a square resolution; e.g., 4k x 4k.
- Doesn't test or indicate support for a duplicate portrait resolution.
