  [HIP] add --offload-compression-level= option (#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.
