Revert "virtgpu_virgl: use blobs NV12 encoder input"
This reverts commit 7eb9e826a71bfe183a99d19ad90cbd58a7babec7.
Reason for revert: b/260322776
Original change's description:
> virtgpu_virgl: use blobs NV12 encoder input
>
> Use blob buffers for encoder NV12 input, even when software access is
> required. This is helpful for ARCVM, since the v4l2_codec2 stack
> sometimes needs to do a format conversion in the guest as the
> virtio-video encoder only supports NV12/I420 input.
>
> Supporting this requires knowing the host buffer layout before creating
> the blob resource. This is done by creating a temporary resource to
> query the layout. To avoid the overhead of querying the host every time
> a buffer is created, the allocator process keeps a cache of the most
> recently used buffer formats and their host layout.
>
> Creating temporary resources to discover host buffer parameters is a bit
> of a cludge. However, since virtgpu_virgl will eventually be deprecated
> in favor of virtgpu_cross_domain, a self-contained and simple approach
> like this gives some nice performance gains on low end devices.
