[WOFF 2.0] Add third_party/brotli

Brotli is the byte-level compression algorithm of WOFF 2.0 font file format.
This patch adds a dependency on the font-compression-reference repository[1]
which includes Brotli decoder. This library will be used by third_party/ots,
as the replacement of LZMA.

WOFF 2.0 feature is currently available behind the
enable-experimental-web-platform-features flag. The Brotli decoder runs in
render processes.
