[jdk17u-dev] RFR: 8281238: TYPE_USE annotations not printed in correct position in toString output

[Liam Miller-Cushon]

This backport of [JDK-8281238](https://bugs.openjdk.org/browse/JDK-8281238) fixes a bug in `TypeMirror#toString` output when printing type annotations.

`TypeMirror#toString` is specified to return a string that is "suitable for representing this type in source code". This fix causes type annotations on qualified names to be printed at the correct location, for example `java.lang. at Annotation String` instead of `@Annotation java.lang.String`.

There was a bug in the initial fix for JDK-8281238, follow-on fix [JDK-8284220](https://bugs.openjdk.org/browse/JDK-8284220) is included in this backport.
