x86/fpu: Add fpu_state_config::legacy_features
The upcoming prctl() which is required to request the permission for a
dynamically enabled feature will also provide an option to retrieve the
supported features. If the CPU does not support XSAVE, the supported
features would be 0 even when the CPU supports FP and SSE.
Provide separate storage for the legacy feature set to avoid that and fill
in the bits in the legacy init function.
