Support @NumberFormat as a meta-annotation the same as @DateTimeFormat.

@NumberFormat(style = NumberFormat.Style.PERCENT)
@Target({ElementType.FIELD})
@Retention(RetentionPolicy.RUNTIME)
public @interface PercentNumber {}

public class TestBean {

    private Double percent;
    // ...
}

Addressed in GitHub commits df1d90f (4.2) and bac012f (4.1.6):

Support @NumberFormat as a meta-annotation

This commit ensures that @NumberFormat can be used as a
meta-annotation, as was already the case for @DateTimeFormat.

In addition, this commit polishes FormattingConversionServiceTests and
MvcNamespaceTests.
