[llvm] [RFC][NFC][AMDGPU] Remove explicit value assignments from `AMDGPU::GPUKind` (PR #146567)

[Shilei Tian via llvm-commits]

https://github.com/shiltian created https://github.com/llvm/llvm-project/pull/146567

We don't seem to rely on the specific values of these enums, so removing the
explicit assignments simplifies the process of adding new targets.
