JVM IR: keep property for $receiver field of optimized delegated properties

For properties which delegate to other property via the getValue
operator from stdlib (see KT-39054), we generate `$receiver` field which
stores the receiver of the property reference used in the delegate. The
problem was that this backing field was missing `correspondingProperty`.
It's needed because it is used as a map key to store static fields in
`JvmCachedDeclarations.getStaticBackingField`. If it's null, accesses to
the static $receiver fields are not remapped correctly in
`RemapObjectFieldAccesses` and
`MoveOrCopyCompanionObjectFieldsLowering`, which led to ICCE or NSFE.
