[vlc-devel] [PATCH] direct3d11: allow 9.3 support by default

On Win7 by default we'll try D3D11 for hardware decoding and it will fail because
it doesn't support all 11.0 for decoding. But support with 9.3 should work and is
indeed supported when forced. Performance wise is should be similar to D3D9 as
D3D9 do some copying internally that we do explicitly in this case with D3D11.

D3D11 is already used when hardware decoding is not used on Win7.

Fixes #19140 with automatic setup.
