RFR: 8306698: Add overloads to MethodTypeDesc::of

Sat Apr 22 16:39:53 UTC 2023

Please review this patch adding two new convenience methods that allows easier access to MethodTypeDesc instances and its associated CSR as well. This is a necessity to allow #13186 to reduce array copies in a few scenarios; the implementation of the two methods will be updated there.
