Auto merge of #146148 - Flakebi:global-addrspace-test, r=Mark-Simulacrum

Add amdgpu test for addrspacecasting global vars and the gpu-kernel calling convention
Add two tests that can now be added, as the amdgpu is merged.
- Global variables are casted to the default address space since #135026
- gpu-kernel calling convention, translatos to amdgpu_kernel #135047
Tracking issue: #135024
