Add DEPS.chromium to share dEQP deps with Chrome.

DEPS.chromium

+# This file is used to manage the ANGLE's dependencies in the Chromium src repo. It is
+# used by gclient to determine what version of each dependency to check out, and
+# where.
+#
+# These deps are duplicated in ANGLE's DEPS file which we use for the standalone
+# build. The dual file setup is necessary because Chromium can only recurse into
+# a single file and we do not want to import all of ANGLE's standalone DEPS.
+#
+# If you make a change to one of these dependencies please also update the
+# standalone DEPS file.
