using keyword this in class property initialization

[Maybeka]

Describe the bug slang does not allow using keyword this in class property initialization. But it should be legal.

To Reproduce the code test.sv:

typedef class B;
class A;
  B b;
  function new(B b);
    this.b = b;
  endfunction
endclass

class B;
  A a = new(this);
endclass

module test;
  B b = new();
endmodule

run slang test.sv:

Top level design units:
    test

test.sv:10:13: error: invalid use of 'this' outside of a non-static method
  A a = new(this);
            ^~~~
