Add detailed documentation for standard Grails application profiles

[jamesfredley]

Introduces new documentation sections and files for each standard Grails application profile, including web, REST API, plugin, web-plugin, rest-api-plugin, and profile profiles.

Resolves: #14695

As a developer perhaps it would be nice to elaborate over the profile profile. I for one don't know how to use it 🙂

@jamesfredley the grails package-plugin is mentioned in the documentation so I guess this #11613 is no longer relevant.
I tested creating a Grails 4.0.4 plugin and I have the package-plugin command, I am not sure it is a Grails issue, probably as missing plugin or dependency in his project....

This is probaly not relevant any more
#14091

The section 6.4 Publishing Profiles (which is outside this PR) has this snippet:

grailsPublish {
        githubSlug = 'foo/bar'
        license {
            name = 'Apache-2.0'
        }
        title = 'My plugin title'
        desc = 'My plugin description'
        developers = [johndoe: 'John Doe']
    }

which should probably be:

grailsPublish {
    githubSlug = 'foo/bar'
    license {
        name = 'Apache-2.0'
    }
    title = 'My profile title'
    desc = 'My profile description'
    developers = [johndoe: 'John Doe']
}

#11613 and #14091 have been updated and closed given package-plugin is available for projects with grails profiles plugin, web-plugin and rest-api-plugin.

@sbglasius Do you think 6.1 - 6.6 on https://docs.grails.org/snapshot/guide/profiles.html#creatingProfiles cover the profile profile well or should we create an issue to add further improvements?
