Add post build task for multiply conditions

[Amerousful]

https://issues.jenkins.io/browse/JENKINS-66055

Problem statement:
Currently, using the postBuildTask method is possible to create only separated check conditions.

Solution:
Create a method to support the creation of multiply chain conditions.

The use case makes sense but the design of the solution could use some improvement. The use of postBuildTaskChainConditions and a list goes against the DSL conventions used elsewhere. Something more in line with existing conventions (both in the regular DSL and the Dynamic DSL) would be:

job('example') {
    publishers {
        postBuildTask {
            logTexts {
                logText {
                    logText 'Build was aborted'
                    operator 'AND'
                }
                logText {
                    logText 'Simulation.*started'
                    operator 'AND'
                }
            }
            script 'git clean -fdx'
        }
    }
}

Implementing this in the regular DSL seems like it would be a lot of effort, and the result seems like it would be hard to maintain. While the Dynamic DSL doesn't seem to work out of the box here, in #1258 we discovered that the regular DSL can be made to delegate to the Dynamic DSL in some cases (albeit without the ability to test those cases in job-dsl-core). Implementing something similar here seems desirable, as we could get all the syntax for tasks "for free" from the Dynamic DSL and not have to maintain custom code in this plugin.
