Sam Brannen 4ae471df01 Resolve all default context configuration within @⁠Nested hierarchy
Prior to this commit, if an enclosing test class (such as one annotated
with @⁠SpringBootTest or simply @⁠ExtendWith(SpringExtension.class))
was not annotated with @⁠ContextConfiguration (or @⁠Import with
@⁠SpringBootTest), the ApplicationContext loaded for a @⁠Nested test
class would not use any default context configuration for the enclosing
test class.

Effectively, a default XML configuration file or static nested
@⁠Configuration class for the enclosing test class was not discovered
by the AbstractTestContextBootstrapper when attempting to build the
MergedContextConfiguration (application context cache key).

To address that, this commit introduces a new
resolveDefaultContextConfigurationAttributes() method in
ContextLoaderUtils which is responsible for creating instances of
ContextConfigurationAttributes for all superclasses and enclosing
classes. This effectively enables AbstractTestContextBootstrapper to
delegate to the resolved SmartContextLoader to properly detect a
default XML configuration file or static nested @⁠Configuration class
even if such classes are not annotated with @⁠ContextConfiguration.

Closes gh-31456
