hw_base_encode: refactor picture allocation/freeing

Browse Source 
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.
