KVM: vmx: Add defines for SGX ENCLS exiting
Hardware support for basic SGX virtualization adds a new execution control (ENCLS_EXITING), VMCS field (ENCLS_EXITING_BITMAP) and exit reason (ENCLS), that enables a VMM to intercept specific ENCLS leaf functions, e.g. to inject faults when the VMM isn't exposing SGX to a VM. When ENCLS_EXITING is enabled, the VMM can set/clear bits in the bitmap to intercept/allow ENCLS leaf functions in non-root, e.g. setting bit 2 in the ENCLS_EXITING_BITMAP will cause ENCLS[EINIT] to VMExit(ENCLS). Note: EXIT_REASON_ENCLS was previously added by commit 1f5199927034 ("KVM: VMX: add missing exit reasons").
