[HIP] add --offload-compression-level= option (llvm#83605)
Added --offload-compression-level= option to clang and -compression-level= option to clang-offload-bundler for controlling compression level. Added support of long distance matching (LDM) for llvm::zstd which is off by default. Enable it for clang-offload-bundler by default since it improves compression rate in general. Change default compression level to 3 for zstd for clang-offload-bundler since it works well for bundle entry size from 1KB to 32MB, which should cover most of the clang-offload-bundler usage. Users can still specify compression level by -compression-level= option if necessary.
