RISC-V: KVM: Factor-out VCPU config into separate sources

Browse Source 
The VCPU config deals with hideleg, hedeleg, henvcfg, and hstateenX
CSR configuration for each VCPU. Factor-out VCPU config into separate
sources so that VCPU config can do things differently for guest HS-mode
and guest VS/VU-mode.
