x86/fpu: Document signal frame layout and portability
The x86 signal frame is designed to be self-describing, with the
'xstate_size' field in the software-reserved bytes indicating the actual
size of the context. This design is required for portability, allowing a
signal frame created on a system with a specific set of xstate features
to be restored on a machine with a different (larger) set of features.
