[lldb] Use packaging module instead of pkg_resources

Use the packaging [1] module for parsing version numbers, instead of
pkg_resources which is distributed with setuptools. I recently switched
over to using the latter, knowing it was deprecated (in favor of the
packaging module) because it comes with Python out of the box. Newer
versions of setuptools have removed `pkg_resources` so we have to use
packaging.
