Revert "Revert "Write dex files to oat file early.""

This reverts commit 919f5536182890d2e03f59b961acf8f7c836ff61.

Fix linker error (Mac build):
Replace inline definition of art::ZipArchive::~ZipArchive()
with an out-of-line definition in zip_archive.cc to avoid
direct reference to CloseArchive() from libart-compiler due
to inlining. Note that libart is linked against -lziparchive
but libart-compiler is not.
