Returns whether a map has a value associated with a given key.

 @example
   map-has-key(("foo": 1, "bar": 2), "foo") => true
   map-has-key(("foo": 1, "bar": 2), "baz") => false
 @overload map_has_key($map, $key)
   @param $map [Sass::Script::Value::Map]
   @param $key [Sass::Script::Value::Base]
 @return [Sass::Script::Value::Bool]
 @raise [ArgumentError] if `$map` is not a map
