Track only qualifier annotations in BeanOverrideHandler #34260
Description
BeanOverrideHandler currently tracks all "field annotations" for bean override fields (such as those annotated with @MockitoBean); however, the intention was to track "qualifier annotations" analogous to what Spring Boot's QualifierDefinition does.
In light of that, we should revise BeanOverrideHandler so that it tracks only qualifier annotations for use in equals() and hashCode().
