Let us sort isa extensions alphabetically in kvm_isa_ext_arr[] and
kvm_riscv_vcpu_isa_disable_allowed() so that future insertions are
more predictable.

We extend the KVM ISA extension ONE_REG interface to allow KVM

extensions for Guest/VM.

Currently, the ISA extension ONE_REG interface only allows enabling or
disabling one extension at a time. To improve this, we extend the ISA
extension ONE_REG interface (similar to SBI extension ONE_REG interface)
so that KVM user space can enable/disable multiple extensions in one
ioctl.

The VCPU ONE_REG interface has grown over time and it will continue
to grow with new ISA extensions and other features. Let us move all
ONE_REG related code to its own source file so that vcpu.c only
focuses only on high-level VCPU functions.
