x86/cpufeatures: Move X86_FEATURE_CALL_DEPTH from bit 18 to bit 19 of word 11, to leave space for WIP X86_FEATURE_SGX_EDECCSSA bit
Reallocate a soft-cpufeatures bit allocated for call-depth tracking
code, which clashes with this recent KVM/SGX patch being worked on:
KVM/VMX: Allow exposing EDECCSSA user leaf function to KVM guest
Instead of reallocating cpufeatures bits in evil merges, make the
allocation explicit.
