Paolo Bonzini 8e0b2b9166 x86/speculation: Use ARCH_CAPABILITIES to skip L1D flush on vmentry ...

Bit 3 of ARCH_CAPABILITIES tells a hypervisor that L1D flush on vmentry is
not needed.  Add a new value to enum vmx_l1d_flush_state, which is used
either if there is no L1TF bug at all, or if bit 3 is set in ARCH_CAPABILITIES.
