Use CFDictionarySetValue to enable low-latency encoding mode.
Since the key is a type of "EncoderSpecification", instead of
"CompressionProperty".

VVCParserContext.au_info is only used once (and in a read-only manner);
but this happens immediately after au_info has been completely
overwritten. Therefore one can just the src structure used to overwrite
au_info directly and remove au_info.
This also means that the whole referencing and unreferncing of au_info
(which duplicates AVBufferRefs CodedBitstreamH266Context and is
therefore of dubious gain) can be removed, as can the AVBufferRef*
contained in PuInfo; this also removes a certain uglyness: Sometimes
these AVBufferRef* were ownership pointers and sometimes not.

The issue is that while decode_slice is guaranteed to never get
called without start_frame, end_frame is not. Moreover, it is
not guaranteed it won't be called twice.
On a badly-broken sample, this is what happens, which leads to
a segfault, as vp->slices_buf doesn't exist, as it has been handed
off for decoding already and isn't owned by the frame.
Return an error as it's indicative that it's a corrupt stream rather
than just missing any slices.
Prevents a segfault.
Should fix integer overflows, and improve encoding results.
