Improve GPU support

[nazar-pc]

Two key fixes here: Windows and linking.

Windows support is fixed (ignore whitespaces, the diff is very small), the solution is described in https://x.com/nazarpc/status/1844098745857667412

Linking was problematic after ROCm introduction because sppark seemed to always link amdhip64, even if only CUDA support was built (and I don't really see why), but dot-asm/sppark#2 fixed it alongside with DX improvements, so I pulled it into our fork at https://github.com/autonomys/sppark/tree/subspace-v1 and now it is good:

I think the next simplification for CI would be to only build containers and then simply extract executables from then instead of building them on the host again.

Still thinking whether it would be a good idea to simply package into zip archive AMD libraries so user doesn't need to install their runtime through a custom repo manually, any opinion?

Code contributor checklist:

• I have read, understood and followed contributing guide

@jim-counter @randywessels @EmilFattakhov FYI, on Windows HIP SDK 6.1.2 from https://www.amd.com/en/developer/resources/rocm-hub/hip-sdk.html is needed.

Specifically just the HIP RTC Runtime should be enough under "HIP Runtime Compiler -> HIP RTC Runtime 6.1.0", everything else can be unchecked (farmer starts with this, but I didn't check if it can plot, so confirmation would be appreciated, "HIP Libraries Runtime 6.1.0" may be hypothetically needed too):

Full installation will take much more time and disk space for no reason.

I think making it easier for users is a good idea, but only if the AMD library license allows us to do that. (Some licenses don’t allow redistribution, and require you to get the libraries from official sources.)

Looks good!
