RFR: 8308152: PropertyDescriptor should work with overridden generic getter method

[Sergey Bylokhov]

Description of the bug, copied from https://github.com/openjdk/jdk/pull/7190


> In jdk 9 we started to sort the list of methods for each class for two reasons:
>  1. We had a number of bugs which state that our JavaBeans randomly does not work, examples: JDK-6807471[1] , JDK-6788525[2], the reason was that the order of methods from Class.getMethods() is not specified.
>  2. We tried to sort methods so the more specific returns types come first, this was done because our logic for selecting the correct method did not work properly. 
> 
> The second issue above was fixed by the separate change [JDK-8196373](https://bugs.openjdk.java.net/browse/JDK-8196373) so now we only need to sort the list of methods in any order and do not care about return types.
> 

Unfortunatly it was found that we have two code paths to create a PropertyDescriptor, one of them is used by the `Introspector.getBeanInfo` and was patched by the [JDK-8196373](https://bugs.openjdk.java.net/browse/JDK-8196373) and another when the PropertyDescriptor is created directly and it still affected by that bug.

The code added by this patch is the same we already use in PropertyInfo.java, see
