Sam Brannen 9c8535f5e4 Compile SpEL expressions that use Optional with null-safe & Elvis operators ...

In Spring Framework 7.0, we introduced support for using `Optional`
with the null-safe and Elvis operators in SpEL expressions; however,
such expressions were previously not compilable.

To address that, this commit introduces a new
insertOptionalUnwrapIfNecessary() method in CodeFlow which effectively
inserts byte code instructions for `myOptional.orElse(null)`, and the
Elvis, Indexer, MethodReference, and PropertyOrFieldReference
implementations have been modified to track the need to unwrap an
`Optional` in compiled mode and delegate to
insertOptionalUnwrapIfNecessary() accordingly.
