[clang] [llvm] [PowerPC] add TargetParser for PPC target (PR #97541)

Wed Jul 3 01:45:58 PDT 2024
https://github.com/chenzheng1030 created https://github.com/llvm/llvm-project/pull/97541
For now only focus on the CPU type, will work on the CPU features part later.
With the CPU handling in TargetParser, clang and llc/opt are able to query common interfaces.
So we can set same default CPU and CPU features with same interfaces.
