Add reflection hint on Publisher for bean destroy support 

Prior to this commit, `DisposableBeanAdapter` supported reactive bean
destroy methods by detected if `Publisher` is available on the
classpath. The AOT engine did not contribute a reflection hint for this
call.

This commit ensures that this reflection hint is registered in all
cases, even if there are no destroy methods detected on beans.

Fixes gh-31278
