Rollup merge of #130873 - taiki-e:ppc64-atomic, r=Amanieu
rustc_target: Add powerpc64 atomic-related features
This adds the following two target features to unstable powerpc_target_feature.
- `partword-atomics`: 8-bit and 16-bit atomic instructions (`l{b,h}arx` and `st{b,h}cx.`) ([definition in LLVM](https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/PowerPC/PPC.td#L170-L172))
- `quadword-atomics`: 128-bit atomic instructions (`lqarx` and `stqcx.`) ([definition in LLVM](https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/PowerPC/PPC.td#L173-L175))
Both features are [available on power8+](https://github.com/llvm/llvm-project/blob/llvmorg-19.1.0/llvm/lib/Target/PowerPC/PPC.td#L408-L422), so enabled by default for `powerpc64le-*` targets.
