Subject: Adapt website to use g3doc sources and bazel.

This adapts the merged website repository to use the image and bazel
build framework. It explicitly avoids the container_image rules provided
by bazel, opting instead to build with direct docker commands when
necessary.

The relevant build commands are incorporated into the top-level
Makefile.
