(CAT-2180) Upgrade rexml to address CVE-2024-49761

Release prep v9.7.0

The functions were using the old legacy function API.  This meant that
when they called `has_interface_with`, they were calling the legacy
implementation of that function and not the v4 API version introduced in
bc218f0.

Only in the v4 API implementation was the modern `networking` structured
fact being used.  The old `parser/functions/has_interface_with.rb`
version still used legacy facts that are now not included in Puppet 8 by
default.

In this commit, we replace the `has_ip_address` and `has_ip_network`
functions with namespaced Puppet language functions, (these functions
are simple enough to not need ruby). Non-namespaced versions are added
(but marked as deprecated) in `lib/puppet/functions`.

The old implementations are removed completely. This is _almost_
certainly not going to be a breaking change for anyone. (Only other
legacy functions which in turn call these functions could be affected).
