8353735: [JVMCI] Allow specifying storage kind of the callee save register

[mur47x111]

Windows x64 ABI considers the upper portions of YMM0-YMM15 and ZMM0-ZMM15 volatile, that is, destroyed on function calls. This PR allows RegisterConfig implementations to refine the storage kind of callee save register, such that JVMCI compiler can exploit this information to avoid saving full width of these registers.

I would add a second sentence describing the Window ABI example so that it's clear why this API exists.
