RFR: 8279798: Javadoc for BasicTabbedPaneUI is inconsistent [v2]

[Alexey Ivanov]

> A number of methods in BasicTabbedPaneUI uses the imperative form of the verb in the documentation instead of the third-person form which describes what the method does.
> 
> For consistency, I updated such descriptions to use the third-person form of the verb.
> 
> I fixed a couple of typos as well.
> 
> I also expanded all the wildcard imports into the specific ones.
