Add woff2 to src/third_party

Add woff2 to src/third_party

This patch adds the woff2 library [1] which is used to decode WOFF 2.0
web font file format. It's going to replace the old version of WOFF 2.0
decoder included in third_party/ots.

Rubber-stamp LGTM.

Could you mention URL/revision in the description? It would be helpful when we
just run `git log`.
