Lynne c39e861a3d vulkan_h264: check if slices_buf exists on end_frame 
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.

Lynne 997d8a7e73 vulkan_decode: reject decoding of frames with no slices 
As per the spec:
VUID-VkVideoDecodeH264PictureInfoKHR-sliceCount-arraylength
sliceCount must be greater than 0

VUID-VkVideoDecodeH265PictureInfoKHR-sliceSegmentCount-arraylength
sliceSegmentCount must be greater than 0

This particularly happens with seeking in field-coded H264.

Lynne 4ff303a7b8 vulkan_decode: simplify and make session parameter generation more robust 
This commit scraps a bool to signal to recreate the session parameters,
but instead destroys them, forcing them to be recreated.

at both places.

Lynne ba8a803236 vulkan_decode: clean up slice handling 
Move the slice offsets buffer to the thread decode context.
It isn't part of the resources for frame decoding, the driver
has to process and finish with it at submission time.
That way, it doesn't need to be alloc'd + freed on every frame.
