Avoid eager init when evaluating DevToolsDataSourceCondition

Previously, DevToolsDataSourceCondition called
getBeanNamesForType(Class) which could trigger unwanted initialization
of lazy init singletons and objects created by FactoryBeans.

This commit updates DevToolsDataSourceCondition to prohibit eager
init when getting the names of the beans of a particular type.

Fixes gh-20430
