[FIR] Desugar increment/decrement in body resolve phase

The expression needs to be resolved first to determine if there is a
receiver that needs to be extracted to a temporary variable. Also, the
special case for prefix increment/decrement on local variable without
delegates requires resolution to check if the variable is local.
