Sam Brannen a07033f3fb Resolve all default context configuration within test class hierarchies
Prior to this commit, if a superclass or 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 subclass or @⁠Nested test class would
not use any default context configuration for the superclass or
enclosing test class.

Effectively, a default XML configuration file or static nested
@⁠Configuration class for the superclass or 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.
