FIR: don't emit SENSELESS_NULL_IN_WHEN when value is always null
...
This case (value is always null) contradicts the error message which says
"Expression under 'when' is never equal to null".

FIR checker: SENSELESS_(COMPARISON|NULL_IN_WHEN)
...
Currently DFA does not set "definitely equal to null" for access to variables that got assigned `null`. For example, FIR should mark the following line as SENSELESS_COMPARISON due to `s = null` above.

The problem is at https://github.com/JetBrains/kotlin/blob/7e9f27436a77de1c76e3705da7aa1fbe8938336b/compiler/fir/resolve/src/org/jetbrains/kotlin/fir/resolve/dfa/FirDataFlowAnalyzer.kt#L1104
For null assignment, ideally the type should be `Nothing?`. This is
addressed in a followup commit instead.

FIR DFA: smartcast variable to Nothing? on null assignment
...
In order to make resolution still work for members not available from
`Nothing`, we track the type without `Nothing?` and use that for
resolution instead.
