stage2: cleanups to --compress-debug-sections

 * make the setting in the linker backend be non-optional; by this time
   all defaults are supposed to be resolved.
 * integrate with `zig cc`
 * change the CLI parsing to match C compiler parsing, allowing
   `--compress-debug-sections` alone to choose a default encoding of
   zlib.
