These have bugs in with the latest HIP-RT and HIP SDK, so just disable them
as we do not expect a fix in time, and rolling back would re-introduce other
bugs. As RDNA1 does not have hardware raytracing, it is also less important
to use HIP-RT.
Note that only RDNA2+ is officially supported by HIP, so these GPUs working
at all is somewhat lucky.

After the recent HIP SDK 6.3 update on Windows, the minimum GPU driver
required to use HIP in Cycles has increased.
This commit increases the required driver version listed in the UI and
adds a check to avoid showing HIP devices if they're below a certain
driver version number as they don't work properly.

* Use .empty() and .data()
* Use nullptr instead of 0
* No else after return
* Simple class member initialization
* Add override for virtual methods
* Include C++ instead of C headers
* Remove some unused includes
* Use default constructors
* Always use braces
* Consistent names in definition and declaration
* Change typedef to using

This commit removes support for Vega GPUs from the AMD HIP backend of
Cycles. This is being done as:
- AMD no longer provides official support for Vega GPUs in their
ROCm software.
- Vega GPUs have rendering artifacts on all supported platforms,
and as a result of the reduction of support from AMD, are unlikely
to be fixed. Rendering artifacts include.
- The incorrect shading of volumes (Windows and Linux)
- Missing intersections on many meshes with HIPRT
- Crashing rendering subsurface scattering materials (Linux)
- And more.

The internal compiler error appears to be gone. Unclear why it appeared in the
first place and why it's gone now. Just random kernel code changes causing it.
Pull Request #104719
Enables Vega and Vega II GPUs as well as Vega APU, using changes in HIP code
to support 64-bit waves and a new HIP SDK version.
Tested with Radeon WX9100, Radeon VII GPUs and Ryzen 7 PRO 5850U with Radeon
Graphics APU.

Basic testing on windows only so far. Will need some testing on Linux as well
when the Linux enablement patch is ready.
Does not enable Vega APUs yet (which would be gfx902 or gfx90c).

* Replace license text in headers with SPDX identifiers.
* Remove specific license info from outdated readme.txt, instead leave details
to the source files.
* Add list of SPDX license identifiers used, and corresponding license texts.
* Update copyright dates while we're at it.

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.
