get_wordwrap_string_size always return the max width of a wordwrapped string

Issue description

The width value returned by get_wordwrap_string_size is always the same (i.e. the max width the string will be with wordwrapping enabled).

While it may not necessarily be a bug, it makes the function useless in the case you want to know the size of a string smaller than the width value given. (And a returned value that is always the same as a given argument is pretty useless in any case)

The wanted behaviour in this case would be something like :

var s = "abc"
var max_size = 50
var string_size = font.get_string_size(s)
var string_size_wordwrap = font.get_wordwrap_string_size(s, max_size)
var string_size_min =  Vector2(min(string_size.x, string_size_wordwrap.x), string_size_wordwrap.y)

Steps to reproduce

print(font.get_wordwrap_string_size("", 50))
will return a size of (50, 24)
