Vulkan video has parameter overrides, where the driver can override the
driver provided parameters with an encoded bitstream where it has made
changes.
This is the support code to encode the bitstream headers for h265
from parameters (vps/sps/pps).

The H264 spec defines a complicated way of layering PPS scaling lists
on top of SPS scaling lists. The details can be found in 7.4.2.1
(seq_scaling_matrix_present_flag semantics) and 7.4.2.2
(pic_scaling_matrix_present_flag semantics).
Both ANV and RADV need to derive the final scaling lists sent to HW
using this logic in order to handle H264 scaling lists correctly.

Vulkan spec doesn't provide any interface for slice decoding while some
devices may require them. So we need to keep this inside.

The video session and video session parameters objects can have a common
base class the drivers can inherit from if needed.
This creates code to parse the h264/h265 parameter sets into common
structs.
v2: add h265 VPS, add a macro for FIND/ADD generations, changes the API
to make generation easier.
