[Clang] Support `--offload-compress` for offload binaries (#227765)
Summary:
https://github.com/llvm/llvm-project/pull/222774 added support for
compressing binaries. This PR does the minimal work required to hook
this up to the existing handling. The end goal is to be able to replace
the bundler in HIP.
The one change is moving the `--verbose` handling from the shared helper
so this can be unified.
