Add native support for @Convert on JPA entities

Browse Source 
This commit infers the reflection hints required for converters
when they are specified with the @Convert annotation at class or
field level.

It also refines the hints generated for @Converter in order
to just generate the construct hint, not the public method one
which should be not needed.

Closes gh-29771
