GDScript: Add lambda syntax parsing

Browse Source 
Lambda syntax is the same as a the function syntax (using the same
`func` keyword) except that the name is optional and it can be embedded
anywhere an expression is expected. E.g.:

    func _ready():
        var my_lambda = func(x):
            print(x)
        my_lambda.call("hello")
