Use zstd to compress debug info in cc libraries
We can save a significant amount of disk space by compressing
debug info in `lld` cc builds. This change configures a build
flag to instruct lld to compress debug info when building cc
libraries. Rather than adding a global config we add this to
each target individually to avoid linker failures on windows
cross build targets.
