Sam Brannen e1720d89fc Don't mutate annotation metadata when merging attrs ...

Prior to this commit, invoking the getMergedAnnotationAttributes()
method in AnnotationReadingVisitorUtils resulted in mutation of the
internal state of the ASM-based annotation metadata supplied to the
method.

This commit fixes this issue by making a copy of the original
AnnotationAttributes for the target annotation before merging attribute
values from the meta-annotation hierarchy.

This commit also introduces a slight performance improvement by
avoiding duplicate processing of the attributes of the target
annotation.

Issue: SPR-11710
