Sam Brannen 4b07edbaeb Reliably resolve generic read/write methods in PropertyDescriptorUtils ...

Prior to this commit, the determineBasicProperties() method in
PropertyDescriptorUtils did not reliably resolve read/write methods in
type hierarchies with generics. This utility method is used by
SimpleBeanInfoFactory which is used by BeanUtils and BeanWrapperImpl.
Thus, failure to reliably resolve read/write JavaBeans methods resulted
in bugs in certain scenarios.

For example, BeanUtils.copyProperties() randomly failed to copy certain
properties if the write method for the property could not be resolved.

To address such issues, this commit revises the implementation of
PropertyDescriptorUtils as follows.

1) Read methods with covariant return types are now consistently
   resolved correctly.

2) If multiple ambiguous write methods are discovered, the algorithm now
   checks for an exact match against the resolved generic parameter type
   as a fallback.

Closes gh-36019
