Simplify dSYM handling

- Previously we would zip the output of dsymutil and then proceed to unzip it.
  Due to the size of dSYM files, this could add a few seconds to all builds
  with dSYMs.
- There's no need to have a DsymOutputType or even Info.plist as all we need
  is the DWARF symbol file; the dSYM is repackaged later on by the bundler.

This change is synchronized with the CROSSTOOL and wrapped_clang via the
`no_dsym_create_zip` feature, which Bazel sets on the CROSSTOOL to inform
wrapped_clang that no zip file should be created for the dSYM.
