Do not synchronize `ApplicationContext` creation in the TestContext framework [SPR-10536]

James Shaw opened SPR-10536 and commented

DefaultCacheAwareContextLoaderDelegate.loadContext() synchronizes access to the ContextCache which means that ApplicationContexts cannot be initialized in parallel.

I tried removing the ContextCache altogether, but this uncovered a deadlock in AbstractBeanFactory. Trying to fix that with a shared lock caused some race condition to autowire a null Environment into a @Configuration class' field.
