Enable DirectX 12 feature level 11.1 (#1117)

Skia supports all DX12 feature levels, see here for example:
https://source.chromium.org/chromium/chromium/src/+/main:third_party/skia/tools/ganesh/d3d/D3DTestUtils.cpp;l=60;drc=cbb0388767d2b8a5a5c1f5484a68fb0ff201561b

It appears however that some GPUs (like Intel(R) HD Graphics 4600) don't
work with Skia's DirectX backend at all. Those adapters should be marked
as unsupported in Skiko instead.

The reason for this change is that the current choice of feature levels
disables support for "good" FL11.1-compatible adapters, for example, the
Parallels Virtual GPU.

Feature level 11.1 is chosen as a safe bet for now since it's
effectively the same as 12.0, with some baseline features of 12.0 being
optional here.
