HHH-20582 Walk superclass auditing data when resolving @OneToOne mappedBy

[brodziakm]

Fixes https://hibernate.atlassian.net/browse/HHH-20582

Envers ToOneRelationMetadataGenerator.checkMappedByAudited (added in HHH-19897 / PR #11175)
validates that the owning side of an inverse @OneToOne is audited, but only inspects the
concrete referenced entity's ClassAuditingData. CollectionMappedByResolver was updated in
the same change to walk superclasses; this brings @OneToOne inverse resolution in line.
Adds MappedByOnSuperclassOneToOneTest reproducing bootstrap failure when mappedBy targets
a property declared on a parent @Entity in a SINGLE_TABLE hierarchy.

Thanks @brodziakm, the fix is looking great. I've added a few suggestions on the test side.

[mbellade]

I know you copied this from the "negative" tests of https://github.com/hibernate/hibernate-orm/pull/11175/changes#diff-4133702339842d4a59cbeeb04c398c116f8bd63c758b9a1eb71bb98ded6acc1a, which is fine, but since we expect this case to work correctly it would be better to use the @EnversTest + @Jpa(annotatedClasses={...}) annotations, and actually persist some entities and verify the mappings and audit trail work as expected.

[mbellade]

Please use explicit entity names for inner class entities and avoid GenerationType.IDENTITY as that is not supported across all dbs.

Suggested change

	@Entity(name = "Account")
	@Audited
	@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
	@DiscriminatorColumn(name = "type")
	public abstract static class Account {
	@Id
	@GeneratedValue

Same as above:

	@Entity(name = "Credential")
