d3d12: Use static_cast instead of dynamic_cast in d3d12_video_enc_h264.cpp

Because we may compile mesa with both rtti=enabled and rtti=disabled because of LLVM
Fixes errors:
../../src/gallium/drivers/d3d12/d3d12_video_enc_h264.cpp:777:7: error: 'dynamic_cast' not permitted with '-fno-rtti'
  777 |       dynamic_cast<d3d12_video_bitstream_builder_h264 *>(pD3D12Enc->m_upBitstreamBuilder.get());
      |       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
