Lynne 9db68ed042 hw_base_encode: refactor picture allocation/freeing 
This commit cleans up and refactors the mess of private state upon
private state that used to be.

Now, FFHWBaseEncodePicture is fully initialized upon call-time,
and, most importantly, this lets APIs which require initialization
data for frames (VkImageViews) to initialize this for both the
input image, and the reconstruction (DPB) image.

Tong Wu e783e45e29 avcodec/hw_base_encode: avoid getting FFHWBaseEncodeContext from avctx 
This patch is to make FFHWBaseEncodeContext a standalone component
and avoid getting FFHWBaseEncodeContext from avctx->priv_data.
This patch also removes some unnecessary AVCodecContext arguments.

For receive_packet call, a small wrapper is introduced.
