Clang: Add some tests for lambda highlighting

Test that local, argument and member variables are highlighted
correctly when referenced inside a lambda

struct LambdaTester
{
    int member = 0;
    void func() {
        const int var = 42, var2 = 84;
        auto lambda = [var, this](int input) {
            return var + input + member; // All variables here
        };
        lambda(var2);
    }
};
