common-mk: Mirror protoctxt.gypi from src/platform/
protoctxt.gypi was added to src/platform/common-mk in CL:189238 but is not yet
mirrored in src/platform2/. This CL copies the file over so that shill can start
using src/platform2/common-mk build files.

+# Helper file to convert text format protobuf files to binary format.
+
+# Note: This file is similar to protoc.gypi, but is kept separate because
+# - They expect different inputs/outputs: both rules would have to set default
+# values for variables that are not really sensible.
+# - protoc.gypi exports a hard dependency, while protoctxt.gypi does not.
+
+# To use this rule, add a target to your gyp file defining:
+# protoc_proto_dir: The directory where the proto definition can be found.
+# protoc_proto_def: Relative path to proto definition from |protoc_proto_dir|.
+# protoc_message_name: The fully qualified name of the message contained in
+# the protobuf.
+# protoc_text_dir: The directory where the text format protobuf[s] can be found.
+# protoc_bin_dir: The full path to the output directory. Note that this path is
+# not relative to the <(SHARED_INTERMEDIATE_DIR). You must ensure that this
+# directory is unique across all platform2 projects to avoid collisions. One
+# way to do this is to include your project name in the directory path.
+# Finally, specify the protobuf files in text format as the sources. These files
+# should have a '.prototxt' file extension.
