scripting: add endswith operator to property filters and RainerScript 
This Implements suffix comparison similar to startswith. Note that we
do intentionally not use libestr functions in order to speed up adaption.
It would otherwise probably take years for distros to upgrade libestr.

With some help of the Codex and Gemini AI Agents.

add 'exists()' script function to check if variable exists

currently set of not.

Sample: if exists($!somevar) then ...

6327e43ea9 config: add include() script object 
This permits to include files (like legacy $IncludeConfig) via a
script object. Needless to say, the script object offers more
features:

- include files can now be
  - required, with rsyslog aborting when not present
  - required, with rsyslog emitting an error message but otherwise
    continuing when not present
  - optional, which means non-present include files will be
    skipped without notice
  This is controlled by the "mode" parameter.
- text can be included form e.g. an environment variable
  --> ex: include(text=`echo $ENVVAR`)

This finally really obsoletes $IncludeConfig.

4ca5e217e2 Adds support for 'reset' statement (it has syntax similar to set 'set', but _unlike_ 'set' always force-sets the given value insteed of conditionally merging it, or not saving it because it is trying to replace an object with a leaf value etc). 
Syntax:

reset $.foo = $!bar;

etc.
