Require annotation signal for constructor binding

Browse Source 
Update `@ConfigurationProperties` constructor binding support to only
apply when a `@ConstructorBinding` annotation is present on either the
type or the specific constructor to use.

Prior to this commit we didn't have a good way to tell when constructor
binding should be used vs regular autowiring.

For convenience, an `@ImmutableConfigurationProperties` meta-annotation
has also been added which is composed of `@ConfigurationProperties` and
`@ConstructorBinding`.

Closes gh-18469
