Automatically build SWIG from source

This change allows Bazel to fetch and build SWIG rather than getting it
from the system. This change also improves the i/o performance of the
SWIG build, makes it hermetically sealed, and ensures tf_py_wrap_cc()
can function correctly across Bazel repositories.
