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

[Yudi Zheng]

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 backing up full width of these registers.
