[PATCH RFC 06/11] KVM: VMX: Split off hyperv_evmcs.{ch}

From: Vitaly Kuznetsov
Date: Tue Oct 10 2023 - 12:04:38 EST

Some Enlightened VMCS related code is needed both by Hyper-V on KVM and
KVM on Hyper-V. As a preparation to making Hyper-V emulation optional,
create dedicated 'hyperv_evmcs.{ch}' files which are used by both.

No functional change intended.
