Track libcore java.lang.reflect API changes

The modifications to Class / Field affect the .txt file
for no good reason: the use of a different generic
variable name results in changes because the tools think
methods have been added / removed when they haven't.

The only interface change from upstream included is adding
"extends AnnotatedElement" to GenericDeclaration. All (platform)
subclasses already did implement this interface. App classes may
be affected but only if they do not currently implement those
methods and they are somehow called.
