Prevent early resolution of factory beans

This commit updates DatabaseInitializationDependencyConfigurer so that
it does not inject the Environment anymore. Doing so in such a low-level
callback can lead to early resolution of factory beans. Rather, this
commit uses the EnvironmentAware callback that short-circuit dependency
resolution.

Closes gh-29475
