compress: change compression providers API to use ABDs
This commit changes the provider compress and decompress API to take ABD
pointers instead of buffer pointers for both data source and
destination. It then updates all providers to match.
This doesn't actually change the providers to do chunked compression,
just changes the API to allow such an update in the future. Helper
macros are added to easily adapt the ABD functions to their buffer-based
implementations.
