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.

In iamf_write_codec_config(), if codec_id equals to AV_CODEC_ID_AAC,
avio_open_dyn_buf() allocated memory would leak. Add ffio_free_dyn_buf()

In sap_write_header(), ff_format_set_url() assign new allocated new_url

We previously had a similar debate regarding realmedia (search for "Codec
