JLD dependency of GPUArrays breaks AMDGPU tests

[luraess]

Since GPUArrays v11.2.4 release the AMDGPU test of GPUArrays fail related to a JLD2 error; see e.g. https://buildkite.com/julialang/amdgpu-dot-jl/builds/3316#019913b0-c058-45ab-8971-f76afaf16fe4/366-572.

Seems to be related to the merged PR #597 which made it to the 11.2.4 release of GPUArrays https://github.com/JuliaGPU/GPUArrays.jl/releases/tag/v11.2.4.

What would be the way to fix this without having to make JLD2 a deps in GPU backend tests (or is this the only way to go)?

Seems AMDGPU got forgotten in #597 (comment).

Closing this as we follow the same approach for now in JuliaGPU/AMDGPU.jl#823.
