RFR: 8366002: Beans.instantiate needs to describe the lookup procedure [v2]

[Phil Race]

> Some text describing the Beans.instantiate lookup process existed only on the method that used the now removed AppletInitializer.
> Since there are two other Beans.instantiate methods, we need to move that text to the remaining methods.
> 
> Note that one of the methods is also deprecated for removal, so it seems prudent to add it to both so that when the next to be removed method is gone, this problem doesn't recur.
> 
> This is a doc. only change. The CSR is ready for review.
