[LLVM] Fail if `LLVM_ENABLE_ZSTD` is `FORCE_ON` but static zstd libraries are not found (#15924) Currently, if we pass `LLVM_USE_STATIC_ZSTD=ON` and `LLVM_ENABLE_ZSTD=FORCE_ON`, we silently ignore zstd and proceed to build the compiler. With `LLVM_ENABLE_ZSTD=FORCE_ON`, we should throw an error instead. Thanks @tcreech-intel for find this.
