9daa541816 d3d12decoder: Fix potential use after free 
A DPB buffer held by codec picture object may not be writable
at the moment, then gst_buffer_make_writable() will unref passed buffer.

Specifically, the use after free or double free can happen if:
* Crop meta of buffer copy is required because of non-zero
  top-left crop position
* zero-copy is possible with crop meta
* A picture was duplicated, interlaced h264 stream for example

Interlaced h264 stream with non-zero top-left crop position
is not very common but it's possible configuration in theory.

Thus gst_buffer_make_writable() should be called with
GstVideoCodecFrame.output_buffer directly.

e2eff3e4a3 d3d12decoder: Fix bitstream buffer usage 
Resource state of a buffer in upload heap should stay in
generic-read although it's effectively in common state. Some drivers
complains about the wrong state.

1b86c9d370 d3d12decoder: Try zero-copy in case of reverse playback too 
In case of tier 1 decoder, always use reference-only picture to avoid
fixed-size pool limitation and output decoded picture without
copy even for negative rate. Also do not use copy queue for GPU to GPU
copy. Copy queue is specialized for upload/download and may occupy
PCIE bandwidth. Use direct queue as recommended by vendors.

0ce6e752e4 d3d12: Use CREATE_NOT_ZEROED heap flag if possible 
Zero initialization would have overhead and it's not required
most cases except for textures. Use CREATE_NOT_ZEROED flag
in case of buffer resource or if a texture will be rendered without any
prior read operation.
