This pulls down the prebuilt ceres libraries and uses them with Bazel to
build and test wpical.
Do note that bazel looks up artifacts used for testing differently than
the other build systems. It wants you to use its runfiles API to find
the dependencies reliably. Add a function to look up the paths for
files, and use runfiles only when building with Bazel to maintain
compatibility with other languages.

This makes it so rules_jvm_external also doesn't package up all the
opencv class files into the final published packages. And is simpler to
maintain.

This sets us up to properly depend on opencv, by introducing the new
helpers, @rules_bzlmodrio_toolchains//cc:cc_shared_import.bzl to import
the shared libraries correctly from opencv.

Pull in some of the fixes merged into the various dependencies. While
we are here, move all the downloads up to the top of the file so they
download in parallel.
