KVM: VMX: Rename "KVM is using eVMCS" static key to match its wrapper

Rename enable_evmcs to __kvm_is_using_evmcs to match its wrapper, and to
avoid confusion with enabling eVMCS for nested virtualization, i.e. have
"enable eVMCS" be reserved for "enable eVMCS support for L1".

No functional change intended.
