Consider an atomic reference `i`, it's FIR representation is
- FirQualifiedAccessExpression
- calleeReference : FirNamedReference
Currently, both of the above FIR elements uses the same PSI element as
the source. Such problems are not present with `this` or `super` because
we manually mark them as `ExplicitThisOrSuperReference`.
This change generalizes the previous `ExplicitThisOrSuperReference` as
`ReferenceInAtomicQualifiedAccess` and fixes it for more cases.
