HHH-19209 Verify and fix ID class generation for inner classes

[cigaly]

Jira issue HHH-19209

• sorting record components when generating ID class
• added tests to check ID class generation from inner classes; fixed minor bug in generated class name
• test classes in core that are using entity (instead of ID) as parameter to find method are annotated with @Exclude to avoid failing tests

My assumption that record component must be alphabetically sorted by name was not correct, so All code and test based on the assumption are now removed.
Due to that change, three existing test cases are now failing:
org.hibernate.orm.test.annotations.formula.JoinFormulaManyToOneLazyFetchingTest,
org.hibernate.orm.test.annotations.formula.JoinFormulaManyToOneNotIgnoreLazyFetchingTest, and
org.hibernate.orm.test.annotations.formula.JoinFormulaOneToOneNotIgnoreLazyFetchingTest.
But this is not caused by changes in this PR.
