Add support for "Any" type

[ghaith]

Is your feature request related to a problem? Please describe.
The norm defines functions that can be used with any parameter, or return any parameter type.

Describe the solution you'd like
The norm defines ANY, ANY_NUM, ANY_BIT, ANY... as types that the other types derive from,
I suggest we use these names as guidance but we introduce a generic representation for these functions
e.g. REF<T: ANY>(in: T)
Deriving from ANY_NUMBER will make sure the T is either integer or float and so on.

Function calls for generic functions will be converted to a typed call
For example : a function with the signature ADD<T: ANY_NUMBER>(in1: T, in2: T) : T will look for a function of signature ADD__INT(in1: INT, in2: INT) : INT if in1 and in2 are passed as INT
The double underscore in the name ensures that the function is not a normal user-defined function.

@ghaith i think this is done with today's merge of #380
