[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.

+Description:
+Brotli is a generic byte-level compression algorithm that is proposed to
+be used at the byte-compression level in WOFF 2.0 font file format.
+
+This library is used by src/third_party/ots, to decode WOFF 2.0 fonts.
+
+The font-compression-reference repository includes WOFF 2.0 encoder and
+tools, but Chrome/Chromium need only files under brotli/dec.
