A DESCRIPTION OF THE PROBLEM :
Currently, creating a `MethodType` that takes more than 1 parameter requires calling the varargs overload `MethodType.methodType(Class, Class, Class...)`, requiring an additional array allocation by the caller (at least until JDK-8164891 is implemented for varargs bridges).

There already are overloads for 0 and 1 parameter respectively.

I propose adding additional overloads for up to 10 parameters (matching the `List.of(…)`, `Map.of(…)`, and `Set.of(…)` overloads).
