Clear all SGX related capabilities if SGX is not fully enabled in IA32_FEATURE_CONTROL or if the SGX1 instruction set isn't supported (impossible on bare metal, theoretically possible in a VM if the VMM is doing something weird). Like SGX itself, SGX Launch Control must be explicitly enabled via a flag in IA32_FEATURE_CONTROL. Clear the SGX_LC capability if Launch Control is not fully enabled (or obviously if SGX itself is disabled). Note that clearing X86_FEATURE_SGX_LC creates a bit of a conundrum regarding the SGXLEPUBKEYHASH MSRs, as it may be desirable to read the MSRs even if they are not writable, e.g. to query the configured key, but clearing the capability leaves no breadcrum for discerning whether or not the MSRs exist. But, such usage will be rare (KVM is the only known case at this time) and not performance critical, so it's not unreasonable to require the use of rdmsr_safe(). Clearing the cap bit eliminates the need for an additional flag to track whether or not Launch Control is truly enabled, which is what we care about the vast majority of the time.
