[SPR-7960][SPR-8386] Supporting declarative configuration of bean definition profiles in the TestContext framework:

- TextContext now works with MergedContextConfiguration instead of locations and loader
- TextContext now builds context caching key from MergedContextConfiguration
- Test context caching is now based on locations, classes, active profiles, and context loader
- TextContext now delegates to SmartContextLoader or ContextLoader as appropriate
- AbstractContextLoader now implements SmartContextLoader
- AbstractGenericContextLoader now sets active profiles in the GenericApplicationContext 
- Introduced integration tests for profile support in the TCF for both XML and annotation config
