Decouple SiteMesh 2 Final Phase - remove GroovyPageLayoutFinder requirement

[codeconsole]

GroovyPageLayoutFinder.groovy is coupled to too many things includingResponseRenderer.groovy

This could be solved by changing

    private GroovyPageLayoutFinder groovyPageLayoutFinder
    private GrailsPluginManager pluginManager

    @Generated
    @Autowired(required = false)
    void setGroovyPageLayoutFinder(GroovyPageLayoutFinder groovyPageLayoutFinder) {
        this.groovyPageLayoutFinder = groovyPageLayoutFinder

to

    private def groovyPageLayoutFinder
    private GrailsPluginManager pluginManager

    @Generated
    @Autowired(required = false)
    @Qualifier("groovyPageLayoutFinder") 
    void setGroovyPageLayoutFinder(def groovyPageLayoutFinder) {
        this.groovyPageLayoutFinder = groovyPageLayoutFinder
    }

but first the constants should be moved out of GroovyPageLayoutFinder and into a new java class since they can be utilized by both SiteMesh 2 and 3.

Plugin Breaking

Because this is a trait, this change would break any plugin controller compiled with a previous version of Grails. So this would require a warning to any Grails users that depend on old plugins with controllers. It probably should not be done until the next major version of Grails, but if that is the case a decision should be made whether to get rid of SiteMesh 2 support altogether. Since SiteMesh 2 hasn't officially been released for Jakarta, if Grails 7 is going to be Jakarta, the simplest route would be to just remove SiteMesh 2 altogether from Grails and go straight to SiteMesh 3.

Here is an example on how this breaks existing plugins:
