RFR: 8241969: Type annotation is not shown for wildcard type in Javadoc

[Hannes Wallnoefer]

Please review a simple fix to show type annotations for wildcard types:

JBS: https://bugs.openjdk.java.net/browse/JDK-8241969
Webrev: http://cr.openjdk.java.net/~hannesw/8241969/webrev.00/jdk.patch

The code generating the wildcard link was just missing a call to generate the annotation.

An appropriate test file was already present in testTypeAnnotations/typeannos/Wildcards.java, I just had to add the missing checks.

Thanks,
Hannes
