KVM: x86: Use static_call() for copy/move encryption context ioctls()
Define and use static_call()s for .vm_{copy,move}_enc_context_from(),
mostly so that the op is defined in kvm-x86-ops.h. This will allow using
KVM_X86_OP in vendor code to wire up the implementation. Any performance
gains eeked out by using static_call() is a happy bonus and not the
primary motiviation.
Opportunistically refactor the code to reduce indentation and keep line
lengths reasonable, and to be consistent when wrapping versus running
a bit over the 80 char soft limit.
