Adds D3D11 input surface support to the MediaFoundation encoder (mfenc),
allowing direct encoding of GPU frames without readback to system memory.
This improves performance and compatibility when used alongside scale_d3d11.

Regarding the while loop in hwcontext_d3d11va get_buffer, I understand
the concern about introducing an unbounded wait. However, there have been
a couple of issues reported in the past that highlight this problem:

The filter should be designed universally rather than expecting to be connected
to something specific at its output.

This commit introduces a new hardware-accelerated video filter, scale_d3d11,
which performs scaling and format conversion using Direct3D 11. The filter
enables
efficient GPU-based scaling and pixel format conversion (p010 to nv12), reducing
CPU overhead and latency in video pipelines.
