vulkan_vp9: Read segment and lf data from cbs

Browse Source 
The previous change 26a2a76346 broke Vulkan decoding because the lf and
segmentation values contained within VP9RawFrameHeader can no longer be
updated.

Read the propogated values from the CBS instead.

(cherry picked from commit 7bfaa6d662)
