Previously, regular bean definitions for configuration properties classes
that attempt to use constructor binding were detected in a bean factory
post-processor, ConfigurationPropertiesBeanDefinitionValidator. This
validation examined every standard bean definition and failed if it
encountered one for a class that should have used constructor binding.
There were two downsides to this approach:
1. Reflection used to identify if the bean should be using constructor
binding triggered class loading that could prevent subsequent
instrumentation by a load-time weaver.
2. The cost of the validation was incurred when there was no
misconfiguration to report.
This commit replaces ConfigurationPropertiesBeanDefinitionValidator
with a failure analyzer. This failure analyzer only runs once a failure
has occurred and the application context is not going to complete
refresh. This avoids causing problems with subsequent instrumentation
and also avoids the cost of validation and error reporting unless there
is an error.

Since Spring Framework 4.3.0.RC2, a default embedded value resolver
has been registered with the bean factory when one is not otherwise
configured. This meant that placeholders in `@Value` would be resolved
with or without PropertyPlaceholderAutoConfiguration defining a
PropertySourcesPlaceholderConfigurer bean. However, placeholders in
bean definitions would only be resolved if a
PropertySourcesPlaceholderConfigurer was defined.
This commit updates PropertyPlaceholderAutoConfigurationTests to align
with this change in Framework. We now test that placeholders are
resolved in `@Value` annotations with or without the auto-configuration
and that placeholders in bean definitions are only resolved with the
auto-configured.
