[Bug]: Semantic API does not create a symbol for parameters in expression function

[SasinduDilshara]

Description

type F function (int, int) returns int;

type R record {
    F f = (a, b) => a; // Issue: symbol for the `a` and `b` is empty.
    F antherF = function(int a, int b) returns int { 
        return b;
    };
};

In the above code, the semantic API gives Optional.empty() for the parameters of the expression function in field a.
