98a5c924fc Cycles: Metal readiness: Specify DeviceQueue::enqueue arg types
This patch adds new arg-type parameters to `DeviceQueue::enqueue` and its overrides. This is in preparation for the Metal backend which needs this information for correct argument encoding.

df00463764 Cycles: add shadow path compaction for GPU rendering
Similar to main path compaction that happens before adding work tiles, this
compacts shadow paths before launching kernels that may add shadow paths.

Only do it when more than 50% of space is wasted.

It's not a clear win in all scenes, some are up to 1.5% slower. Likely caused
by different order of scheduling kernels having an unpredictable performance
impact. Still feels like compaction is just the right thing to avoid cases
where a few shadow paths can hold up a lot of main paths.

f0df0e9e07 Fix: Add cast to atof for CYCLES_CONCURRENT_STATES_FACTOR env variable parsing.
The conversion from double to float was causing a build failure.

ba4e227def HIP device code cleanup and fix for high VRAM usage
This patch cleans up code for HIP device and makes it more consistent with the CUDA code.
It also fixes the issue with high VRAM usage on AMD cards using HIP allowing better performance and usage on cards like 6600XT.
Added a check in intern/cycles/kernel/bvh/bvh_util.h to prevent compiler error with hipcc

044a77352f Cycles: add HIP device support for AMD GPUs
NOTE: this feature is not ready for user testing, and not yet enabled in daily
builds. It is being merged now for easier collaboration on development.

HIP is a heterogenous compute interface allowing C++ code to be executed on
GPUs similar to CUDA. It is intended to bring back AMD GPU rendering support
on Windows and Linux.

https://github.com/ROCm-Developer-Tools/HIP.

As of the time of writing, it should compile and run on Linux with existing
HIP compilers and driver runtimes. Publicly available compilers and drivers
for Windows will come later.

See task T91571 for more details on the current status and work remaining
to be done.
