Update `SpringFactoriesLoader` so that `null` is never used for the
cache key. Prior to this commit, calling `forDefaultResourceLocation`
with `null` and `ClassUtils.getDefaultClassLoader()` would provide
different `SpringFactoriesLoader` instances rather than making use
of a single shared cached instance.

The antlr-based SpEL expression grammar file (SpringExpressions.g) was
introduced during initial development and prototyping of the Spring
Expression language; however, it was quickly abandoned in favor of a
handcrafted implementation. Consequently, it has become obsolete over
time and has never been actively maintained.
This commit therefore removes the obsolete SpEL expression grammar file.

A static nested class does not keep an implicit reference to its
enclosing instance.
This prevents a common cause of memory leaks and uses less memory per
instance of the class.

Update `BeanDefinitionPropertiesCodeGenerator` so that hints are
generated for property values. This restores functionality that was
inadvertently removed during refactoring.

Prior to this commit, the `name` attribute in @ModelAttribute was not
supported when using WebFlux. This is because MethodParameter was used
instead of SynthesizingMethodParameter when retrieving the
@ModelAttribute annotation. In other words, @AliasFor was not honored
because the annotation was not synthesized. Consequently, only the
`value` attribute was supported in WebFlux when specifying a custom name
via @ModelAttribute.
This commit fixes this by using SynthesizingMethodParameter to retrieve
the @ModelAttribute annotation.

Update `RegisteredBean` bean class detection to not consider
singletons. Prior to this commit, any beans that had been instantiated
could return the wrong class, especially if they were implemented using
a lambda.
