Simplify WORKSPACE setup and update ancient deps

By removing a single unused `bzl_library` target, rules_cc no longer has
any dependencies that would need to be loaded by a dependency macro. The
existing macro is made a no-op.

The few needed Bazel Federation dependencies are inlined and, in the
case of bazel_skylib and abseil-py, updated to modern versions.

Also reorders `WORKSPACE` to list direct dependencies first and keeps
`MODULE.bazel` in sync with the dependency versions used in WORKSPACE.

The `ubuntu1604` CI pipeline is removed as the version of Python used by
it is no longer supported and the distribution is EOL. Instead, a new
pipeline is added to check the Bzlmod build.
