[JENKINS-27299] Define disabled in ParameterizedJob rather than AbstractProject (#2866)

* Offering default methods on ParameterizedJob.

* Javadoc typo.

* Cleaner use of default methods in ParameterizedJob.

* Need to pick up https://github.com/infradna/bridge-method-injector/pull/15 to be able to build.

* Sketch of pulling disabled functionality into ParameterizedJob.

* EnableJobCommandTest.groovy → EnableJobCommandTest.java, and replacing deprecated Remoting-based CLI calls with CLICommandInvoker.

* All CLI commands could be broken by a missing CLI.*.shortDescription key on just one!

* Forgot to move CLI method short descriptions to new package.

* Needed a @CLIResolver for ParameterizedJob. Adding an OptionHandler while we are here.

* Trying to fix up access-modifier versions; started failing in CI today for unknown reasons.

* Introduced <p:makeDisabled/> by analogy with <p:config-disableBuild/>.

* Using new type bounds.

* access-modifier 1.11 released.

* MatrixProject and MavenModuleSet both expect to have access to makeDisabled.jelly.

* Trying to generalize some more.

* Minor simplification.

* [JENKINS-34716] Generalizing doPolling and schedulePolling.

* isBuildable

* Obsolete comment.

* Updated comments.

* bridge-method-injector 1.17

* Unfortunately AbstractProject.schedulePolling cannot delegate to SCMTriggerItem.

* bridge-method-injector 1.17
