Sahar A. Kashi 6363181af9 Cycles: HIP-RT 2.5 integration and gfx12 support

This change brings the following improvements on the user level
- Support of GPUs with gfx12 architecture
- New HIP-RT library which in addition to the gfx12 support brings
  various bug-fixes.

The known limitation of gfx12 is that OpenImageDenoiser does not yet
support this GPU architecture. This means that while Cycles will use the
full advantage of the gfx12 (including hardware accelerated ray-tracing),
denoising will only be possible on CPU, or secondary gfx11 or below GPU.
This is something that requires a change in OIDN and it is to late to do
it for Blender 4.4, but it is something to look forward for Blender 4.5.

The gfx12 changes for the pre-compiled kernels is rather trivial,
so it comes together (in the same PR) as the bigger HIP-RT change.

On the development side this change brings the following improvements:
- One step compile and link (much simpler CMake rules)
- Embedding BVH binaries in hiprt dll (which makes it easier to package
  and load, without relying on special path configuration)

Pipeline Config

The yaml configuration file is used by buildbot build pipeline update-code step.

The file allows to set branches or specific commits for both git submodules and svn artifacts. Can also define various build package versions for use by build workers. Especially useful in experimental and release branches.

NOTE:

The configuration file is NOT used by the ../utils/make_update.py script.
That will implemented in the future.
