Manage HarfBuzz dependency using DEPS mechanism

Remove src/ from Chromium repo and retrieve HarfBuzz sources from the
mirror at [1].

Cherry picks can be done by HarfBuzz OWNERS by pushing new branches to
refs/heads/chromium/ of [1].

This was tested and confirmed working in::
https://chromium-review.googlesource.com/c/chromium/src/+/937502

 Description:
 This is harfbuzz-ng, a new implementation of harfbuzz with a different
 API from the old one.
 
-This copy of harfbuzz is usually updated by downloading the release tarball from
-http://www.freedesktop.org/software/harfbuzz/release/ , removing files in src,
-copying *.h *.hh *.cc (except for the files below) from the tarball's src folder
-over to src, then checking for removed or added files and update our build
-recipes in BUILD.gn and harfbuzz.gyp accordingly, update the NEWS file from
-HarfBuzz' release notes, and bump the version numbers in README.chromium.
+This copy of harfbuzz is updated by putting the new commit hash matching one in
+https://chromium.googlesource.com/external/github.com/harfbuzz/harfbuzz/ to the
+top level DEPS file. When upgrading, check whether files have been added or
+removed in upstream and whether the BUILD.gn file needs to be updated to reflect
+that.
 
-Currently the following files from HarfBuzz are unused and not copied:
+Chromium-local cherry picks or patches can be done by pushing new branches to
+refs/heads/chromium/ of [1]. The set of HarfBuzz OWNERS has write rights to this
+part of the tree. We suggest to follow a pattern of naming branches needed for
+Chromium revisions by the chromium milestone number. For example, if a
+cherry-pick is needed for M65, push to "refs/heads/chromium/m65" and reference
+the new commit in DEPS. Take a look at
+https://chromium-review.googlesource.com/c/chromium/src/+/937502 for an example.
+
+Currently we are intentionally not building the following files from HarfBuzz.
