Reduce size of the package artifacts

[youwuyou]

• Remove unnecessary packages
• Use weakdeps instead

It would be desirable to have optional weak dependencies instead of having to fetch all artifacts. As users are likely to just use CUDA.jl or AMDGPU.jl in the future but not all of them at the same time. See also the example here

We could set some packages as weak dependencies, as an example from DiffEqGPU.jl here

[weakdeps]
AMDGPU = "21141c5a-9bdb-4563-92ae-f87d6854732e"
CUDA = "052768ef-5323-5732-b1bb-66c8b64840ba"
Metal = "dde4c033-4e86-420c-a63e-0dd931031962"
oneAPI = "8f75cd03-7ff8-4ecb-9b8f-daf728133b1b"
