RFR: 8185831: Psuedo selectors do not appear to work in Node.lookupAll() [v3]

[Sai Pradeep Dandem]

> **Issue:**
> Using pseudo classes in programmatic query using Node.lookupAll() or Node.lookup() gives unexpected results.
> 
> **Cause:**
> There is no check for checking the psuedo states matching in the applies() method of SimpleSelector.java. So checking for "applies()" alone is not sufficient in lookup() method.
> 
> **Fix:**
> Included an extra check for the psuedo states to match.
